Spatial Division Multiplexing for Cold-Atom-Based Quantum Memory

Project description

Space division multiplexing enables high-capacity quantum networks

Optical quantum memories that detect and store photon quantum states for later retrieval are essential components in quantum information. Funded by the Marie Skłodowska-Curie Actions programme, the Multiplex project plans to employ space division multiplexing, a technique that creates and harnesses parallel quantum links and enables vast increases in network transmission capacity. The new multiplexed quantum memory is expected to bring quantum networks a step closer to reality. To achieve their aims, researchers will leverage a state-of-the-art memory that they developed in a previous project, which has demonstrated around 90 % efficiency in storing and retrieving single photons.

Objective

Optical quantum memory, a device that enables the storage and retrieval of photonic qubits, is an essential component for a wide range of applications in quantum information science. The host demonstrated state-of-the-art memory based on large ensembles of cold atoms, with a storage-and-retrieval efficiency close to 90% for single photons. With this milestone reached, a timely and crucial effort is to develop multiplexed memories. This, in turn, should lead to higher-capacity network channels, bringing quantum networks one step closer to reality. In this context, the proposed research will uniquely adapt and exploit Space Division Multiplexing, a booming approach in classical telecommunications, to create and harness parallelized quantum links. The fellow, with a strong background in atomic physics and light shaping, will use his expertise to develop the project efficiently while expanding his skill-set to quantum information networks and developing his independence and leadership during the fellowship.
