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…
Hybrid noiseless subsystems for quantum communication over optical fibers
Jonathan L. Ball, Konrad Banaszek
We derive the general structure of noiseless subsystems for optical radiation contained in a sequence of pulses undergoing collective depolarization in an optical fiber. This resul…
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…
