We show that modulating the damping rate of a microwave resonator generates a vacuum squeezed state of arbitrary squeezing strength, thereby constituting a mechanism allowing perfect squeezing. Given the recent experimental realizations in circuit QED of a microwave resonator with a tunable damping rate [Yin et al., Phys. Rev. Lett. 110, 107001 (2013)], superconducting circuits are an ideal playground to implement this technique. By dispersively coupling a qubit to the microwave resonator, it is possible to obtain qubit-state dependent squeezing.", "revisions": [ { "version": "v2", "updated": "2014-01-28T02:21:50.000Z" } ], "analyses": { "subjects": [ "42.50.Pq", "03.65.Yz", "03.67.Lx", "85.25.-j" ], "keywords": [ "circuit quantum electrodynamics", "perfect squeezing", "damping modulation", "dissipation-driven quantum state", "damping rate" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review A", "doi": "10.1103/PhysRevA.89.013820", "year": 2014, "month": "Jan", "volume": 89, "number": 1, "pages": "013820" }, "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014PhRvA..89a3820D" } } }
