Ultimate limits for sensing of fields and forces are set by the quantum noise of a sensor. Entanglement allows for suppression of such noise and for achieving sensitivity beyond standard quantum limits. Applicability of quantum optical sensing is oft

Squeezed light from an oscillator measured at the rate of oscillation

Autor: Bærentsen, Christian, Fedorov, Sergey A., Østfeldt, Christoffer, Balabas, Mikhail V., Zeuthen, Emil, Polzik, Eugene S.

Publikováno v: Nat Commun 15, 4146 (2024)

Continuous measurements of the position of an oscillator become projective on position eigenstates when the measurements are made faster than the coherent evolution. We evidence an effect of this transition on a spin oscillator within an ensemble of

Abstract Sufficiently fast continuous measurements of the position of an oscillator approach measurements projective on position eigenstates. We evidence the transition into the projective regime for a spin oscillator within an ensemble of 2 × 1010

Trajectories without quantum uncertainties in composite systems with disparate energy spectra

Autor: Zeuthen, Emil, Polzik, Eugene S., Khalili, Farid Ya.

It is well established that measurement-induced quantum back action (QBA) can be eliminated in composite systems by engineering so-called quantum-mechanics-free subspaces (QMFSs) of commuting variables, leading to a trajectory of a quantum system wit
