Quantum noise eater for a single photonic qubit
Miroslav Gavenda, Lucie Čelechovská, Miloslav Dušek +1
We propose a quantum noise eater for a single qubit and experimentally verify its performance for recovery of a superposition carried by a dual-rail photonic qubit. We consider a c…
Visibility bound caused by a distinguishable noise particle
Miroslav Gavenda, Lucie Celechovska, Jan Soubusta +2
We investigate how distinguishability of a "noise" particle degrades interference of the "signal" particle. The signal, represented by an equatorial state of a photonic qubit, is m…
Complete analysis of measurement-induced entanglement localization on a three-photon system
Miroslav Gavenda, Radim Filip, Eleonora Nagali +2
We discuss both theoretically and experimentally elementary two-photon polarization entanglement localization after break of entanglement caused by linear coupling of environmental…
Entanglement localization after a coupling to incoherent noisy system
Fabio Sciarrino, Eleonora Nagali, Francesco De Martini +2
We report the experimental realization of entanglement localization which restores polarization entanglement completely redirected after a linear coupling with incoherent and noisy…
Quantum adaptation of noisy channels
Miroslav Gavenda, Radim Filip
Probabilistic quantum filtering is proposed to properly adapt sequential independent quantum channels in order to stop sudden death of entanglement. In the adaptation, the quantum…
Entanglement concentration after a multi-interactions channel
Eleonora Nagali, Fabio Sciarrino, Francesco De Martini +2
Different procedures have been developed in order to recover entanglement after propagation over a noisy channel. Besides a certain amount of noise, entanglement is completely lost…
