Experimental realization of programmable quantum gate
Michal Micuda, Miroslav Jezek, Miloslav Dusek +1
We experimentally demonstrate a programmable single-qubit quantum gate. This device applies a unitary phase shift operation to a data qubit with the value of the phase shift being…
Preparation of distilled and purified continuous variable entangled states
Boris Hage, Aiko Samblowski, James DiGuglielmo +3
The distribution of entangled states of light over long distances is a major challenge in the field of quantum information. Optical losses, phase diffusion and mixing with thermal…
A No-Go Theorem for Gaussian Quantum Error Correction
Julien Niset, Jaromir Fiurasek, Nicolas J. Cerf
It is proven that Gaussian operations are of no use for protecting Gaussian states against Gaussian errors in quantum communication protocols. Specifically, we introduce a new quan…
Experimental asymmetric phase-covariant quantum cloning of polarization qubits
Jan Soubusta, Lucie Bartuskova, Antonin Cernoch +2
We report on two optical realizations of the asymmetric phase-covariant cloning machines for polarization states of single photons. The experimental setups combine two-ph…
Linear optical Fredkin gate based on partial-SWAP gate
Jaromir Fiurasek
We propose a scheme for linear optical quantum Fredkin gate based on the combination of recently experimentally demonstrated linear optical partial SWAP gate and controlled-Z gates…
