Description
About Quandela: Quandela is a European deeptech scale-up building modular, scalable and energy-efficient photonic quantum computers, accessible both on the cloud and on-premise. With a team of more than 140 people, we develop our own hardware and software stack, from semiconductor quantum emitters to quantum control systems and algorithms. Our ambition is to turn cutting-edge quantum optics into operational quantum computing systems. Within this roadmap, hybrid architectures combining photonic qubits and spin-based quantum memories play a central role in enabling scalable cluster-state quantum computing. About this position: Located at IPVF in Massy, this position is part of the Semiconductor R&D division and integrated within the Spin Cluster / Cooling team. The team develops experimental platforms enabling spin-photon and spin-spin entanglement. Within this framework, your role will focus on stabilizing and improving spin-photon cluster state generation while implementing fast optical control schemes operating at nanosecond time scales. Working at the interface between theory and experiment, you will translate cluster-state protocols into robust and reproducible laboratory implementations, contributing directly to demonstrator milestones and helping move these concepts toward scalable hardware.
