Exponentially Improved Quantum memory

Project description

Boosting interference suppresses light scattering in efficient quantum memory devices

Quantum memory is an interface between light and matter (atoms) based on the storage and retrieval of photonic quantum information or the quantum state of a photon. An overarching goal in quantum optics is to enhance the efficiency and control of interactions between photons and atomic media. Spontaneous emission in which photons are absorbed by atoms and then scattered in undesirable ways is a major challenge. Selective radiance is a phenomenon recently described which enables significant suppression of scattering through strong interference in emission between atoms. The EU-funded ExIQ project is evaluating this theoretical phenomenon experimentally with the goal of demonstrating quantum memory performance with a very small margin of error, supporting the development of future quantum networks.
