New invention keeps qubits of light stable at room temperature

Researchers from University of Copenhagen have developed a new technique that keeps quantum bits of light stable at room temperature instead of only working at -270 degrees. Their discovery saves power and money and is a ...

Researchers realize coherent storage of light over one hour

Remote quantum distribution on the ground is limited because of the loss of photons in optical fibers. One solution for remote quantum communication lies in quantum memories: photons are stored in long-lived quantum memory ...

A survey on optical memory and optical RAM technologies

Over the past decades, 'storing light' has appeared as a rather controversial concept, given that a photon's inherent nature hinders its spatial confinement. The first research efforts in demonstrating optical memory functionality ...
