Here we describe its experimental observation in an electronic harmonic oscillator. We use a superconducting qubit as a nonlinear probe of the phase, which is otherwise unobservable due to the linearity of the oscillator. We show that the geometric phase is, for a variety of cyclic paths, proportional to the area enclosed in the quadrature plane. At the transition to the nonadiabatic regime, we study corrections to the phase and dephasing of the qubit caused by qubit-resonator entanglement. In particular, we identify parameters for which this dephasing mechanism is negligible even in the nonadiabatic regime. The demonstrated controllability makes our system a versatile tool to study geometric phases in open quantum systems and to investigate their potential for quantum information processing."}],"extern":1,"type":"journal_article"},{"_id":"1784","acknowledgement":"This work was supported by the European Research Council (ERC) through a Starting Grant and by ETHZ","year":"2012","status":"public","publication_status":"published","title":"Observation of entanglement between itinerant microwave photons and a superconducting qubit","publisher":"American Physical Society","intvolume":" 109","author":[{"last_name":"Eichler","first_name":"Christopher","full_name":"Eichler, Christopher"},{"first_name":"C","last_name":"Lang","full_name":"Lang, C"},{"orcid":"0000-0001-8112-028X","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","last_name":"Fink","first_name":"Johannes M","full_name":"Johannes Fink"},{"first_name":"J","last_name":"Govenius","full_name":"Govenius, J"},{"first_name":"Stefan","last_name":"Filipp","full_name":"Filipp, Stefan"},{"last_name":"Wallraff","first_name":"Andreas","full_name":"Wallraff, Andreas"}],"date_updated":"2021-01-12T06:53:10Z","date_created":"2018-12-11T11:53:59Z","volume":109,"type":"journal_article","abstract":[{"text":"A localized qubit entangled with a propagating quantum field is well suited to study nonlocal aspects of quantum mechanics and may also provide a channel to communicate between spatially separated nodes in a quantum network.

Cell type transcriptomes carried enough information to categorize cells into morphological classes and types. Several genes that were specifically expressed in particular retinal circuit elements, such as inhibitory neuron types, are associated with eye diseases.

This multi-protein complex with an intricate evolutionary history originated from the unification of prebuilt modules of hydrogenases and transporters. Using recently determined crystallographic structures of complex I we reanalyzed evolutionarily related complexes that couple oxidoreduction to trans-membrane ion translocation. Our analysis points to the previously unnoticed structural homology of the electron input module of formate dehydrogenlyases and subunit NuoG of complex I. We also show that all related to complex I hydrogenases likely operate via a conformation driven mechanism with structural changes generated in the conserved coupling site located at the interface of subunits NuoB/D/H. The coupling apparently originated once in evolutionary history, together with subunit NuoH joining hydrogenase and transport modules. Analysis of quinone oxidoreduction properties and the structure of complex I allows us to suggest a fully reversible coupling mechanism. Our model predicts that: 1) proton access to the ketone groups of the bound quinone is rigorously controlled by the protein, 2) the negative electric charge of the anionic ubiquinol head group is a major driving force for conformational changes."}],"publist_id":"5108","issue":"10","status":"public","publication_status":"published","title":"The coupling mechanism of respiratory complex i - A structural and evolutionary perspective","publisher":"Elsevier","intvolume":" 1817","acknowledgement":"The work in authors' laboratory was funded by the Medical Research Council.","_id":"1976","year":"2012","date_updated":"2019-04-26T07:22:06Z","date_created":"2018-12-11T11:55:00Z","volume":1817,"author":[{"full_name":"Efremov, Rouslan G","last_name":"Efremov","first_name":"Rouslan"},{"orcid":"0000-0002-0977-7989","id":"338D39FE-F248-11E8-B48F-1D18A9856A87","last_name":"Sazanov","first_name":"Leonid A","full_name":"Leonid Sazanov"}]},{"day":"01","month":"06","doi":"10.1016/j.jsb.2012.03.005","date_published":"2012-06-01T00:00:00Z","publication":"Journal of Structural Biology","citation":{"ista":"Efremov R, Sazanov LA. 2012.

Surprisingly, interaction between trimers is mediated exclusively by lipids, without direct protein-protein contacts. Multiple ordered lipids are observed and many of them occupy identical positions independently of the space group, identifying preferential interaction sites of lipid acyl chains.
