LightOn goes Quantum

As compact replacements for fully-fledged optical circuits, and as an alternative to integrated photonics circuits, this novel range of devices is a compelling contender for scalable photonic linear quantum optical computing. Starting from the interfacing of several qubits in its first generation, we plan to increase the circuit size in future iterations, with the aim to rapidly demonstrate a quantum advantage. In this context, a key feature of these devices is the ability to offer low losses, all-to-all circuit connectivity, and easy reconfigurability at any circuit size.
