On the distillation and purification of phase-diffused squeezed states
B. Hage, A. Franzen, J. DiGuglielmo +3
Recently it was discovered that non-Gaussian decoherence processes, such as phase-diffusion, can be counteracted by purification and distillation protocols that are solely built on…
Demonstration of a squeezed light enhanced power- and signal-recycled Michelson interferometer
Henning Vahlbruch, Simon Chelkowski, Boris Hage +3
We report on the experimental combination of three advanced interferometer techniques for gravitational wave detection, namely power-recycling, detuned signal-recycling and squeeze…
Coherent control of vacuum squeezing in the Gravitational-Wave Detection Band
Henning Vahlbruch, Simon Chelkowski, Boris Hage +3
We propose and demonstrate a coherent control scheme for stable phase locking of squeezed vacuum fields. We focus on sideband fields at frequencies from 10Hz to 10kHz which is a fr…
Experimental demonstration of continuous variable purification of squeezed states
A. Franzen, B. Hage, J. DiGuglielmo +2
We report on the first experimental demonstration of purification of nonclassical continuous variable states. The protocol uses two copies of phase-diffused states overlapped on a…
Observation of squeezed light with 10dB quantum noise reduction
Henning Vahlbruch, Moritz Mehmet, Nico Lastzka +6
Squeezing of light's quantum noise requires temporal rearranging of photons. This again corresponds to creation of quantum correlations between individual photons. Squeezed light i…
