Scalable Entangled-Photon based Optical Quantum Computers Project

Abstract and objectives:

Quantum computers are one of the most promising technologies of the future, such devices should be capable of solving problems that are impossible even for the most powerful super computers nowadays. At Quandela, we chose to take this challenge using photons. In fact, photons, being chargeless and massless, are the ideal qubit materials since they are the only elementary particles with no decoherence, thus minimizing the loss of information. Based on over 25 years of research at the Center for Nanoscience and Nanotechnology (C2N, CNRS and Université Paris-Saclay), we demonstrated the world's first efficient emission of single photons powered by our unique semiconductor-based technology (Nature Photonics, 2016). In just a few years, we completed the design and construction of PROMETHEUS which is the first standalone and easy to use single photon source.

Based on this unique technology, we released MOSAIQ, the first full-stack photonic quantum computing platform in the world. MOSAIQ is designed and built to be modular, reconfigurable, interconnected and therefore scalable. It integrates state-of-the-art technologies such as PROMETHEUS, programmable photonic integrated circuits, efficient read-out devices and the associated operating system plus the software stack, such as PERCEVAL, an open-source framework to control and simulate hardware and algorithm layer.

The main objectives of SEPOQC are:

Improve the performances (brightness, purity, reproducibility) of the single photon sources in order to bring optical quantum computers into an unexplored regime, with near-deterministic flow of single and linearly entangled photons. The homogeneity of the semiconductor wafers will be improved in order to increase the fabrication volumes with a high reproducibility.

Develop a new generation of opto-electronic modules that are at the core of our quantum computing platform for the efficient routing and manipulation of photons. The objective is to increase the number of quantum bits to several dozen by minimizing the optical losses, improving the speed of active elements and ensuring a high stability of the whole system.

Develop a library of quantum algorithms and the next generation of software simulating and controlling Quandela quantum computer.
