Eliminating photon transport in long-baseline optical interferometry using quantum memories
Yousef K. Chahine, Chaohan Cui, William DeRocco +11
In this paper, we describe the fundamental operating mechanisms of optical interferometry using quantum memory and entanglement. We show how these remove the optical delay line bot…

Heralded quasi-deterministic entanglement sources based on spontaneous parametric down-conversion
Yousef K. Chahine, J. Gabriel Richardson, Evan J. Katz +2
A double-heralding technique is presented for producing heralded entangled photon pairs from spontaneous parametric down-conversion (SPDC). Compared to the swap-heralded schemes st…

Modeling Entanglement-Based Quantum Key Distribution for the NASA Quantum Communications Analysis Suite
Michael J. P. Kuban, Ian R. Nemitz, Yousef K. Chahine
One of the most practical, and sought after, applications of quantum mechanics in the field of information science is the use of entanglement distribution to communicate quantum in…
