We study the dynamics of the resonant interaction of up to N=3 two-level systems and a single mode of the electromagnetic field sharing a single excitation dynamically. We observe coherent vacuum Rabi oscillations and their nonlinear √N speedup by tracking the populations of all qubits and the resonator in time. We use quantum state tomography to show explicitly that the dynamics generates maximally entangled states of the W class in a time limited only by the collective interaction rate. We use an entanglement witness and the 3-tangle to characterize the state whose fidelity F=78% is limited in our experiments by crosstalk arising during the simultaneous qubit manipulations which is absent in a sequential approach with F=91%."}],"oa":1,"status":"public","title":"Demonstrating W-type entanglement of Dicke states in resonant cavity quantum electrodynamics","date_updated":"2021-01-12T06:53:10Z","date_created":"2018-12-11T11:53:59Z","author":[{"full_name":"Mlynek, Jonas A","last_name":"Mlynek","first_name":"Jonas"},{"last_name":"Abdumalikov","first_name":"Abdufarrukh","full_name":"Abdumalikov, Abdufarrukh A"},{"first_name":"Johannes M","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8112-028X","last_name":"Fink","full_name":"Johannes Fink"},{"full_name":"Steffen, L.
