Quantum Computing Service

The platform enabling researchers to access beyond-classical computational resources

We are advancing the state of the art in quantum algorithms and applications by granting access to Google’s quantum computing hardware. With the Quantum Computing Service, researchers with approved projects can run quantum programs remotely on Google’s latest quantum processors like Sycamore with 50+ qubits.

Early Access

We offer a quantum computing service to scientists developing algorithms for noisy-intermediate-scale quantum processors like Sycamore. The goal is to advance NISQ state-of-the-art in new algorithms, tools, and characterizations that lead to useful applications. Approved projects will run programs on Sycamore via our Quantum Engine API, and user feedback will improve the service.

We are currently collaborating with a group of early access partners and will welcome new applications in 2021.
