Worldwide, enormous efforts are directed toward the development of the so‐called quantum
internet. Turning this long‐sought‐after dream into reality is a great challenge that will …

Quantum memory, which maps photonic quantum information into a stationary medium and
retrieves it at a chosen time, plays a vital role in the advancement of quantum information …

Quantum repeater networks require independent absorptive quantum memories capable of
storing and retrieving indistinguishable photons to perform high-repetition entanglement …

We investigate the interplay between gravity and the quantum coherence present in the
state of a pulse of light propagating in curved spacetime. We first introduce an operational …

Here, we show an ultralow-noise regime of operation in a simple quantum memory in warm
Rb 87 atomic vapor. By modeling the quantum dynamics of four-level room-temperature …

Bose-Einstein condensates are a promising platform for optical quantum memories but
suffer from several decoherence mechanisms, leading to short memory lifetimes. While …

We present a theoretical investigation on the quantum memory of photonic polarization
qubits via electromagnetically induced transparency (EIT). The system we consider is a …
