Creation of a quantum oscillator by classical control
Stefan Danilishin, Helge Müller-Ebhardt, Henning Rehbein +7
As a pure quantum state is being approached via linear feedback, and the occupation number approaches and eventually goes below unity, optimal control becomes crucial. We obtain th…
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…
Detuned Twin-Signal-Recycling for ultra-high precision interferometers
Andre Thuering, Roman Schnabel, Harald Lueck +1
We propose a new interferometer technique for high precision phase measurements such as those in gravitational wave detection. The technique utilizes a pair of optically coupled re…
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…
