Pasqal is a French neutral-atom quantum computing company headquartered in Palaiseau, France and co-founded in 2019 by 2022 Physics Nobel Laureate Alain Aspect. Pasqal builds commercial-grade neutral-atom quantum processors (the Fresnel QPU family) that use arrays of laser-trapped Rydberg atoms to run both analog and digital quantum programs, and packages them as on-premise systems and as Pasqal Cloud Services — a pay-as-you-go quantum computing platform also distributed through Google Cloud, Microsoft Azure Quantum, OVHcloud, and AWS partners. The developer surface is anchored by the open-source Pulser SDK, the pasqal-cloud Python SDK, and the Pasqal Cloud Services REST API.
