How to measure squeezing and entanglement of Gaussian states without homodyning
Jaromir Fiurasek, Nicolas J. Cerf
We propose a scheme for measuring the squeezing, purity, and entanglement of Gaussian states of light that does not require homodyne detection. The suggested setup only needs beam…
Reversibility of continuous-variable quantum cloning
R. Filip, J. Fiurasek, P. Marek
We analyze a reversibility of optimal Gaussian quantum cloning of a coherent state using only local operations on the clones and classical communication between them and p…
Probabilistic quantum multimeters
Jaromir Fiurasek, Miloslav Dusek
We propose quantum devices that can realize probabilistically different projective measurements on a qubit. The desired measurement basis is selected by the quantum state of a prog…
Conditional generation of arbitrary multimode entangled states of light with linear optics
J. Fiurasek, S. Massar, N. J. Cerf
We propose a universal scheme for the probabilistic generation of an arbitrary multimode entangled state of light with finite expansion in Fock basis. The suggested setup involves…
Unitary Gate Synthesis for Continuous Variable Systems
Jaromir Fiurasek
We investigate the synthesis of continuous-variable two-mode unitary gates in the setting where two modes A and B are coupled by a fixed quadratic Hamiltonian H. The gate synthesis…
Entanglement generation in continuously coupled parametric generators
Jiri Herec, Jaromir Fiurasek, Ladislav Mista
We investigate a compact source of entanglement. This device is composed of a pair of linearly coupled nonlinear waveguides operating by means of degenerate parametric downconversi…
