Towards Einstein-Podolsky-Rosen quantum channel multiplexing
Boris Hage, Aiko Samblowski, Roman Schnabel
A single broadband squeezed field constitutes a quantum communication resource that is sufficient for the realization of a large number N of quantum channels based on distributed E…
Multiple copy distillation and purification of phase diffused squeezed states
Petr Marek, Jaromir Fiurasek, Boris Hage +3
We provide a detailed theoretical analysis of multiple copy purification and distillation protocols for phase diffused squeezed states of light. The standard iterative distillation…
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…
Squeezed-field injection for gravitational wave interferometers
Henning Vahlbruch, Simon Chelkowski, Boris Hage +3
In a recent table-top experiment we demonstrated the compatibility of three advanced interferometer techniques for gravitational wave detection, namely power-recycling, detuned sig…
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…
Experimental characterization of frequency dependent squeezed light
Simon Chelkowski, Henning Vahlbruch, Boris Hage +4
We report on the demonstration of broadband squeezed laser beams that show a frequency dependent orientation of the squeezing ellipse. Carrier frequency as well as quadrature angle…
Experimental characterization of Gaussian quantum communication channels
James DiGuglielmo, Boris Hage, Alexander Franzen +2
We present a full experimental characterization of continuous variable quantum communication channels established by shared entanglement together with local operations and classica…
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…
