Optical photons are powerful carriers of quantum information, which can be delivered in free
space by satellites or in fibers on the ground over long distances. Entanglement of quantum …

An optical quantum memory is a device that can store photonic quantum information and
release it after a controlled time. It is an essential component for overcoming channel losses …

Gravitational redshift is discussed in the context of quantum photons propagating in curved
spacetime. A brief introduction to modelling realistic photons is first presented and the effect …
