Hugues de Riedmatten’s ICFO team develops quantum memory

Researchers led by Hugues de Riedmatten, ICREA Professor at the Institute of Photonic Sciences (ICFO) in Barcelona, have demonstrated a quantum memory capable of storing single photons for the longest duration yet achieved in a solid-state system, the company says. This advance, detailed in Physical Review Letters, addresses a critical challenge in building the quantum internet: maintaining the fragile quantum state of information long enough to synchronize distant network segments. The ICFO team’s work uses a novel protocol to counteract decoherence, bringing practical quantum networks closer to reality. “We are continuously sending…
