QuMOMI

Beyond the first prospects for optical control of microwave qubits and long-distance optical transfer of microwave quantum information, QuMOMI technology will enable the optical entanglement of two distant microwave qubits. These results will facilitate the scale-up and connectivity of quantum computing architectures, by opening up an interface between microwave qubits and silicon photonics.

When it comes to quantum information, inefficient conversion can result in classical statistical mixing. High efficiency, low added noise, good understanding and control of thermal effects are essential to develop a converter that correctly processes quantum information. These aspects will be addressed in detail in QuMOMI, to demonstrate efficient microwave-optical conversion of quantum information and optically generate entanglement between distant microwave quantum nodes.

Although the devices that will be used in quantum computing in the future are not known at this stage, we believe that the QuMOMI interface will be key to overcoming many of the challenges in the field of quantum technologies, by naturally bridging ongoing developments in quantum photonics and quantum microwaves, on a silicon platform compatible with large-scale integration.
