text: Contraction and flow of the actin cell cortex have emerged as a common principle
by which cells reorganize their cytoplasm and take shape. However, how these cortical
flows interact with adjacent cytoplasmic components, changing their form and localization,
and how this affects cytoplasmic organization and cell shape remains unclear.
Here we show that in ascidian oocytes, the cooperative activities of cortical
actomyosin flows and deformation of the adjacent mitochondria-rich myoplasm drive
oocyte cytoplasmic reorganization and shape changes following fertilization. We
show that vegetal-directed cortical actomyosin flows, established upon oocyte
fertilization, lead to both the accumulation of cortical actin at the vegetal
pole of the zygote and compression and local buckling of the adjacent elastic
solid-like myoplasm layer due to friction forces generated at their interface.
Once cortical flows have ceased, the multiple myoplasm buckles resolve into one
larger buckle, which again drives the formation of the contraction pole—a protuberance
of the zygote’s vegetal pole where maternal mRNAs accumulate. Thus, our findings
reveal a mechanism where cortical actomyosin network flows determine cytoplasmic
reorganization and cell shape by deforming adjacent cytoplasmic components through
friction forces.

text: 'Reaching a high cavity population with a coherent pump in the strong-coupling
regime of a single-atom laser is impossible due to the photon blockade effect.
In this Letter, we experimentally demonstrate that in a single-atom maser based
on a transmon strongly coupled to two resonators, it is possible to pump over
a dozen photons into the system. The first high-quality resonator plays the role
of a usual lasing cavity, and the second one presents a controlled dissipation
channel, bolstering population inversion, and modifies the energy-level structure
to lift the blockade. As confirmation of the lasing action, we observe conventional
laser features such as a narrowing of the emission linewidth and external signal
amplification. Additionally, we report unique single-atom features: self-quenching
and several lasing thresholds.'

text: The ability to control the direction of scattered light is crucial to provide
flexibility and scalability for a wide range of on-chip applications, such as
integrated photonics, quantum information processing, and nonlinear optics. Tunable
directionality can be achieved by applying external magnetic fields that modify
optical selection rules, by using nonlinear effects, or interactions with vibrations.
However, these approaches are less suitable to control microwave photon propagation
inside integrated superconducting quantum devices. Here, we demonstrate on-demand
tunable directional scattering based on two periodically modulated transmon qubits
coupled to a transmission line at a fixed distance. By changing the relative phase
between the modulation tones, we realize unidirectional forward or backward photon
scattering. Such an in-situ switchable mirror represents a versatile tool for
intra- and inter-chip microwave photonic processors. In the future, a lattice
of qubits can be used to realize topological circuits that exhibit strong nonreciprocity
or chirality.

text: Quantum entanglement is a key resource in currently developed quantum technologies.
Sharing this fragile property between superconducting microwave circuits and optical
or atomic systems would enable new functionalities, but this has been hindered
by an energy scale mismatch of >104 and the resulting mutually imposed loss and
noise. In this work, we created and verified entanglement between microwave and
optical fields in a millikelvin environment. Using an optically pulsed superconducting
electro-optical device, we show entanglement between propagating microwave and
optical fields in the continuous variable domain. This achievement not only paves
the way for entanglement between superconducting circuits and telecom wavelength
light, but also has wide-ranging implications for hybrid quantum networks in the
context of modularization, scaling, sensing, and cross-platform verification.

text: "About a 100 years ago, we discovered that our universe is inherently noisy,
that is, measuring any physical quantity with a precision beyond a certain point
is not possible because of an omnipresent inherent noise. We call this - the quantum
noise. Certain physical processes allow this quantum noise to get correlated in
conjugate physical variables. These quantum correlations can be used to go beyond
the potential of our inherently noisy universe and obtain a quantum advantage
over the classical applications. \r\n\r\nQuantum noise being inherent also means
that, at the fundamental level, the physical quantities are not well defined and
therefore, objects can stay in multiple states at the same time. For example,
the position of a particle not being well defined means that the particle is in
multiple positions at the same time. About 4 decades ago, we started exploring
the possibility of using objects which can be in multiple states at the same time
to increase the dimensionality in computation. Thus, the field of quantum computing
was born. We discovered that using quantum entanglement, a property closely related
to quantum correlations, can be used to speed up computation of certain problems,
such as factorisation of large numbers, faster than any known classical algorithm.
Thus began the pursuit to make quantum computers a reality. \r\n\r\nTill date,
we have explored quantum control over many physical systems including photons,
spins, atoms, ions and even simple circuits made up of superconducting material.
However, there persists one ubiquitous theme. The more readily a system interacts
with an external field or matter, the more easily we can control it. But this
also means that such a system can easily interact with a noisy environment and
quickly lose its coherence. Consequently, such systems like electron spins need
to be protected from the environment to ensure the longevity of their coherence.
Other systems like nuclear spins are naturally protected as they do not interact
easily with the environment. But, due to the same reason, it is harder to interact
with such systems. \r\n\r\nAfter decades of experimentation with various systems,
we are convinced that no one type of quantum system would be the best for all
the quantum applications. We would need hybrid systems which are all interconnected
- much like the current internet where all sorts of devices can all talk to each
other - but now for quantum devices. A quantum internet. \r\n\r\nOptical photons
are the best contenders to carry information for the quantum internet. They can
carry quantum information cheaply and without much loss - the same reasons which
has made them the backbone of our current internet. Following this direction,
many systems, like trapped ions, have already demonstrated successful quantum
links over a large distances using optical photons. However, some of the most
promising contenders for quantum computing which are based on microwave frequencies
have been left behind. This is because high energy optical photons can adversely
affect fragile low-energy microwave systems. \r\n\r\nIn this thesis, we present
substantial progress on this missing quantum link between microwave and optics
using electrooptical nonlinearities in lithium niobate. The nonlinearities are
enhanced by using resonant cavities for all the involved modes leading to observation
of strong direct coupling between optical and microwave frequencies. With this
strong coupling we are not only able to achieve almost 100\\% internal conversion
efficiency with low added noise, thus presenting a quantum-enabled transducer,
but also we are able to observe novel effects such as cooling of a microwave mode
using optics. The strong coupling regime also leads to direct observation of dynamical
backaction effect between microwave and optical frequencies which are studied
in detail here. Finally, we also report first observation of microwave-optics
entanglement in form of two-mode squeezed vacuum squeezed 0.7dB below vacuum level.
\r\nWith this new bridge between microwave and optics, the microwave-based quantum
technologies can finally be a part of a quantum network which is based on optical
photons - putting us one step closer to a future with quantum internet. "

text: Recent quantum technologies have established precise quantum control of various
microscopic systems using electromagnetic waves. Interfaces based on cryogenic
cavity electro-optic systems are particularly promising, due to the direct interaction
between microwave and optical fields in the quantum regime. Quantum optical control
of superconducting microwave circuits has been precluded so far due to the weak
electro-optical coupling as well as quasi-particles induced by the pump laser.
Here we report the coherent control of a superconducting microwave cavity using
laser pulses in a multimode electro-optical device at millikelvin temperature
with near-unity cooperativity. Both the stationary and instantaneous responses
of the microwave and optical modes comply with the coherent electro-optical interaction,
and reveal only minuscule amount of excess back-action with an unanticipated time
delay. Our demonstration enables wide ranges of applications beyond quantum transductions,
from squeezing and quantum non-demolition measurements of microwave fields, to
entanglement generation and hybrid quantum networks.

text: 'State-of-the-art transmon qubits rely on large capacitors, which systematically
improve their coherence due to reduced surface-loss participation. However, this
approach increases both the footprint and the parasitic cross-coupling and is
ultimately limited by radiation losses—a potential roadblock for scaling up quantum
processors to millions of qubits. In this work we present transmon qubits with
sizes as low as 36 × 39 µm2 with 100-nm-wide vacuum-gap capacitors that are micromachined
from commercial silicon-on-insulator wafers and shadow evaporated with aluminum.
We achieve a vacuum participation ratio up to 99.6% in an in-plane design that
is compatible with standard coplanar circuits. Qubit relaxationtime measurements
for small gaps with high zero-point electric field variance of up to 22 V/m reveal
a double exponential decay indicating comparably strong qubit interaction with
long-lived two-level systems. The exceptionally high selectivity of up to 20 dB
to the superconductor-vacuum interface allows us to precisely back out the sub-single-photon
dielectric loss tangent of aluminum oxide previously exposed to ambient conditions.
In terms of future scaling potential, we achieve a ratio of qubit quality factor
to a footprint area equal to 20 µm−2, which is comparable with the highest T1
devices relying on larger geometries, a value that could improve substantially
for lower surface-loss superconductors. '

text: Quantum state tomography is an essential component of modern quantum technology.
In application to continuous-variable harmonic-oscillator systems, such as the
electromagnetic field, existing tomography methods typically reconstruct the state
in discrete bases, and are hence limited to states with relatively low amplitudes
and energies. Here, we overcome this limitation by utilizing a feed-forward neural
network to obtain the density matrix directly in the continuous position basis.
An important benefit of our approach is the ability to choose specific regions
in the phase space for detailed reconstruction. This results in a relatively slow
scaling of the amount of resources required for the reconstruction with the state
amplitude, and hence allows us to dramatically increase the range of amplitudes
accessible with our method.

text: Currently available quantum processors are dominated by noise, which severely
limits their applicability and motivates the search for new physical qubit encodings.
In this work, we introduce the inductively shunted transmon, a weakly flux-tunable
superconducting qubit that offers charge offset protection for all levels and
a 20-fold reduction in flux dispersion compared to the state-of-the-art resulting
in a constant coherence over a full flux quantum. The parabolic confinement provided
by the inductive shunt as well as the linearity of the geometric superinductor
facilitates a high-power readout that resolves quantum jumps with a fidelity and
QND-ness of >90% and without the need for a Josephson parametric amplifier. Moreover,
the device reveals quantum tunneling physics between the two prepared fluxon ground
states with a measured average decay time of up to 3.5 h. In the future, fast
time-domain control of the transition matrix elements could offer a new path forward
to also achieve full qubit control in the decay-protected fluxon basis.

text: Arrays of Josephson junctions are governed by a competition between superconductivity
and repulsive Coulomb interactions, and are expected to exhibit diverging low-temperature
resistance when interactions exceed a critical level. Here we report a study of
the transport and microwave response of Josephson arrays with interactions exceeding
this level. Contrary to expectations, we observe that the array resistance drops
dramatically as the temperature is decreased—reminiscent of superconducting behaviour—and
then saturates at low temperature. Applying a magnetic field, we eventually observe
a transition to a highly resistive regime. These observations can be understood
within a theoretical picture that accounts for the effect of thermal fluctuations
on the insulating phase. On the basis of the agreement between experiment and
theory, we suggest that apparent superconductivity in our Josephson arrays arises
from melting the zero-temperature insulator.

text: Microwave-optics entanglement is a vital component for building hybrid quantum
networks. Here, a new mechanism for preparing stationary entanglement between
microwave and optical cavity fields in a cavity optomagnomechanical system is
proposed. It consists of a magnon mode in a ferrimagnetic crystal that couples
directly to a microwave cavity mode via the magnetic dipole interaction and indirectly
to an optical cavity through the deformation displacement of the crystal. The
mechanical displacement is induced by the magnetostrictive force and coupled to
the optical cavity via radiation pressure. Both the opto- and magnomechanical
couplings are dispersive. Magnon–phonon entanglement is created via magnomechanical
parametric down-conversion, which is further distributed to optical and microwave
photons via simultaneous optomechanical beamsplitter interaction and electromagnonic
state-swap interaction, yielding stationary microwave-optics entanglement. The
microwave-optics entanglement is robust against thermal noise, which will find
broad potential applications in quantum networks and quantum information processing
with hybrid quantum systems.

text: Solid-state microwave systems offer strong interactions for fast quantum logic
and sensing but photons at telecom wavelength are the ideal choice for high-density
low-loss quantum interconnects. A general-purpose interface that can make use
of single photon effects requires < 1 input noise quanta, which has remained elusive
due to either low efficiency or pump induced heating. Here we demonstrate coherent
electro-optic modulation on nanosecond-timescales with only 0.16+0.02−0.01 microwave
input noise photons with a total bidirectional transduction efficiency of 8.7%
(or up to 15% with 0.41+0.02−0.02), as required for near-term heralded quantum
network protocols. The use of short and high-power optical pump pulses also enables
near-unity cooperativity of the electro-optic interaction leading to an internal
pure conversion efficiency of up to 99.5%. Together with the low mode occupancy
this provides evidence for electro-optic laser cooling and vacuum amplification
as predicted a decade ago.

text: 'Magnetic-field-resilient superconducting circuits enable sensing applications
and hybrid quantum computing architectures involving spin or topological qubits
and electromechanical elements, as well as studying flux noise and quasiparticle
loss. We investigate the effect of in-plane magnetic fields up to 1 T on the spectrum
and coherence times of thin-film three-dimensional aluminum transmons. Using a
copper cavity, unaffected by strong magnetic fields, we can probe solely the effect
of magnetic fields on the transmons. We present data on a single-junction and
a superconducting-quantum-interference-device (SQUID) transmon that are cooled
down in the same cavity. As expected, the transmon frequencies decrease with increasing
field, due to suppression of the superconducting gap and a geometric Fraunhofer-like
contribution. Nevertheless, the thin-film transmons show strong magnetic field
resilience: both transmons display microsecond coherence up to at least 0.65 T,
and T1 remains above 1μs over the entire measurable range. SQUID spectroscopy
is feasible up to 1 T, the limit of our magnet. We conclude that thin-film aluminum
Josephson junctions are suitable hardware for superconducting circuits in the
high-magnetic-field regime.'

text: Micro- and nanoscale optical or microwave cavities are used in a wide range
of classical applications and quantum science experiments, ranging from precision
measurements, laser technologies to quantum control of mechanical motion. The
dissipative photon loss via absorption, present to some extent in any optical
cavity, is known to introduce thermo-optical effects and thereby impose fundamental
limits on precision measurements. Here, we theoretically and experimentally reveal
that such dissipative photon absorption can result in quantum feedback via in-loop
field detection of the absorbed optical field, leading to the intracavity field
fluctuations to be squashed or antisquashed. A closed-loop dissipative quantum
feedback to the cavity field arises. Strikingly, this modifies the optical cavity
susceptibility in coherent response measurements (capable of both increasing or
decreasing the bare cavity linewidth) and causes excess noise and correlations
in incoherent interferometric optomechanical measurements using a cavity, that
is parametrically coupled to a mechanical oscillator. We experimentally observe
such unanticipated dissipative dynamics in optomechanical spectroscopy of sideband-cooled
optomechanical crystal cavitiess at both cryogenic temperature (approximately
8 K) and ambient conditions. The dissipative feedback introduces effective modifications
to the optical cavity linewidth and the optomechanical scattering rate and gives
rise to excess imprecision noise in the interferometric quantum measurement of
mechanical motion. Such dissipative feedback differs fundamentally from a quantum
nondemolition feedback, e.g., optical Kerr squeezing. The dissipative feedback
itself always results in an antisqueezed out-of-loop optical field, while it can
enhance the coexisting Kerr squeezing under certain conditions. Our result applies
to cavity spectroscopy in both optical and superconducting microwave cavities,
and equally applies to any dissipative feedback mechanism of different bandwidth
inside the cavity. It has wide-ranging implications for future dissipation engineering,
such as dissipation enhanced sideband cooling and Kerr squeezing, quantum frequency
conversion, and nonreciprocity in photonic systems.

text: "Over the past few years, the field of quantum information science has seen
tremendous progress toward realizing large-scale quantum computers. With demonstrations
of quantum computers outperforming classical computers for a select range of problems,1–3
we have finally entered the noisy, intermediate-scale quantum (NISQ) computing
era. While the quantum computers of today are technological marvels, they are
not yet error corrected, and it is unclear whether any system will scale beyond
a few hundred logical qubits without significant changes to architecture and control
schemes. Today's quantum systems are analogous to the ENIAC (Electronic Numerical
Integrator And Computer) and EDVAC (Electronic Discrete Variable Automatic Computer)
systems of the 1940s, which ran on vacuum tubes. These machines were built on
a solid, nominally scalable architecture and when they were developed, nobody
could have predicted the development of the transistor and the impact of the resulting
semiconductor industry. Simply put, the computers of today are nothing like the
early computers of the 1940s. We believe that the qubits of future fault-tolerant
quantum systems will look quite different from the qubits of the NISQ machines
in operation today. This Special Topic issue is devoted to new and emerging quantum
systems with a focus on enabling technologies that can eventually lead to the
quantum analog to the transistor. We have solicited both research4–18 and perspective
articles19–21 to discuss new and emerging qubit systems with a focus on novel
materials, encodings, and architectures. We are proud to present a collection
that touches on a wide range of technologies including superconductors,7–13,21
semiconductors,15–17,19 and individual atomic qubits.18\r\n"
