Measurement of a microwave field amplitude beyond the standard quantum limit
M. Penasa, S. Gerlich, T. Rybarczyk +6
We report a quantum measurement beyond the standard quantum limit (SQL) for the amplitude of a small displacement acting on a cavity field. This measurement uses as resource an ent…
Past quantum state analysis of the photon number evolution in a cavity
Théo Rybarczyk, Stefan Gerlich, Bruno Peaudecerf +8
A quantum system can be monitored through repeated interactions with meters, followed by their detection. The state of the system at time t is thus conditioned on the information o…
Field locked to Fock state by quantum feedback with single photon corrections
X. Zhou, I. Dotsenko, B. Peaudecerf +6
Fock states with photon numbers n up to 7 are prepared on demand in a microwave superconducting cavity by a quantum feedback procedure which reverses decoherence-induced quantum ju…
Real-time quantum feedback prepares and stabilizes photon number states
Clément Sayrin, Igor Dotsenko, Xingxing Zhou +9
Feedback loops are at the heart of most classical control procedures. A controller compares the signal measured by a sensor with the target value. It adjusts then an actuator in or…
