Currently quantum computing has proven to make fast and accurate logical calculations and promises to drastically change the field of computing. One of the main limitations are the short coherence times of qubits, which precludes information storage, and the possibility of making distant communications between quantum registers that is challenging using microwave photons (these are resonant with qubit transitions). The MOCA project proposes the use of an integrated chip combining superconducting resonators with optical waveguides and cavities that converts the microwave photons to optical photons. The chip is then coupled to an ensemble of cold atoms for the long term storage of the information.
