Experimental realization of linear-optical partial SWAP gates
A. Cernoch, J. Soubusta, L. Bartuskova +2
We present a linear-optical implementation of a class of two-qubit partial SWAP gates for polarization states of photons. Different gate operations, including the SWAP and entangli…
Quantum cloning a pair of orthogonally polarized photons with linear optics
Jaromir Fiurasek, Nicolas J. Cerf
A linear optical probabilistic scheme for the optimal cloning of a pair of orthogonally-polarized photons is devised, based on single- and two-photon interferences. It consists in…
Preparation of entangled states of two photons in several spatial modes
Karel Lemr, Jaromir Fiurasek
We describe a protocol capable of preparing an arbitrary state of two photons in several spatial modes using pairs of photons generated by spontaneous parametric down-conversion, l…
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…
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…
