Directional asymmetry of quantum channels

2020 · Frontiers in Optics / Laser Science

We study the influence of propagation direction on the transmission of polarization entanglement in a channel affected by modal loss and decoherence. We demonstrate symmetric entanglement reduction and asymmetric nonlocal compensation.

Characterizing the noise output by a fiber-based entangled photon source

2023

By simultaneously measuring individual and coincidence counts of two single photon detectors connected to a fiber-based entangled photon source and fitting the results with a theoretical model of the photon generation rates, we determine the …
