New Phase in Optical Bose-Einstein Condensate Raises Quantum Communication Possibilities
BONN, Germany, April 12, 2021 — Led by University of Bonn professor Martin Weitz, researchers have observed a previously unknown phase transition in the optical Bose-Einstein condensate. The state is known as an overdamped phase, and it may be relevant for encrypted quantum communication. “If suitable quantum mechanically entangled states occur in coupled light condensates, this may be interesting for transmitting quantum-encrypted messages between multiple participants,” said Fahri Emre Öztürk, a
