Squeezed state purification with linear optics and feed forward
O. Glöckl, U. L. Andersen, R. Filip +2
A scheme for optimal and deterministic linear optical purification of mixed squeezed Gaussian states is proposed and experimentally demonstrated. The scheme requires only linear op…
Universal optical amplification without nonlinearity
V. Josse, M. Sabuncu, N. J. Cerf +2
We propose and experimentally realize a new scheme for universal phase-insensitive optical amplification. The presented scheme relies only on linear optics and homodyne detection,…
Many-body quantum dynamics of polarisation squeezing in optical fibre
J. F. Corney, P. D. Drummond, J. Heersink +3
We report new experiments that test quantum dynamical predictions of polarization squeezing for ultrashort photonic pulses in a birefringent fibre, including all relevant dissipati…
Witnessing effective entanglement in a continuous variable prepare&measure setup and application to a QKD scheme using postselection
S. Lorenz, J. Rigas, M. Heid +3
We report an experimental demonstration of effective entanglement in a prepare&measure type of quantum key distribution protocol. Coherent polarization states and heterodyne measur…
Experimental distillation of squeezing from non-Gaussian quantum states
J. Heersink, Ch. Marquardt, R. Dong +4
We show theoretically and experimentally that single copy distillation of squeezing from continuous variable non-Gaussian states is possible using linear optics and conditional hom…
Cloning of Gaussian states by linear optics
Stefano Olivares, Matteo G. A. Paris, Ulrik L. Andersen
We analyze in details a scheme for cloning of Gaussian states based on linear optical components and homodyne detection recently demonstrated by U. L. Andersen et al. [PRL 94 24050…
