Decoherence-free subspaces and subsystems for a collectively depolarizing bosonic channel
Jonathan L. Ball, Konrad Banaszek
We discuss the structure of decoherence-free subsystems for a bosonic channel affected by collective depolarization. A single use of the channel is defined as a transmission of a p…
Characterization of the non-classical nature of conditionally prepared single photons
Alfred B. U'Ren, Christine Silberhorn, Jonathan L. Ball +2
A reliable single photon source is a prerequisite for linear optical quantum computation and for secure quantum key distribution. A criterion yielding a conclusive test of the sing…
Blind dispersion compensation for optical coherence tomography
Konrad Banaszek, Aleksandr S. Radunsky, Ian A. Walmsley
We propose a numerical method for compensating dispersion effects in optical coherence tomography that does not require a priori knowledge of dispersive properties of the sample. T…
Experimental demonstration of entanglement-enhanced classical communication over a quantum channel with correlated noise
K. Banaszek, A. Dragan, W. Wasilewski +1
We present an experiment demonstrating entanglement-enhanced classical communication capacity of a quantum channel with correlated noise. The channel is modelled by a fiber optic l…
