Efficient time-bin qubit analyzer compatible with multimode optical channels

2015 · arXiv (Cornell University)

Time-bin encoded photonic qubits are robust against decoherence in birefringent media such as optical fibers, which has led to many successful quantum communication demonstrations, including a Mach-Zehnder interferometer-based system, plug-and-play quantum key distribution (QKD), differential …

Entanglement verification with detection-efficiency mismatch

2017 · Physical Review A

The security analysis of quantum key distribution is difficult to perform when there is efficiency mismatch between various threshold detectors involved in an experimental setup. Even the verification that the device actually performs in the …
