Modular optical quantum computing
By Niccolo Somaschi, cofounder, Quandela
 |
Recent breakthroughs achieved by the quantum photonics community towards the realization of large optical quantum computing (QC) platforms were based on either a “full integration” approach [1] or via an interconnected modular-like platform [2,3]. Both architectures were based on well identified fundamental blocks whose independent technical progresses drive the full platform computation capacity.
These hardware building blocks, consist in quantum light sources, active routers, processors/interferometers and detectors; independently of the computational scheme (linear optical QC or measurement-based QC) one can extract the required performance thresholds of each component which allow to scale up, or not, the computing platform. Besides, these same modules could integrate in diverse applications, ranging from quantum communication and networks to quantum metrology, encompassing the full spectrum of quantum technologies enabled by light.
At Quandela we work on building these fundamental optoelectronics modules and interconnect them to realize reconfigurable quantum computing platforms in an efficient and scalable way. All these components are designed to guarantee plug-and-play operation and reconfigurability, permitting their efficient implementation and adaptability to different quantum technologies and applications.
