Explore the possibilities of quantum

Google Quantum AI is advancing the state of the art of quantum computing and developing the tools for researchers to operate beyond classical capabilities.

Featured publications

Our research efforts aim to build quantum processors and develop novel quantum algorithms.

Quantum Supremacy Using a Programmable Superconducting Processor

On Oct 23, 2019, Google announced it performed a calculation on a quantum processor in 300 seconds that would be impractical with the algorithms available at the time.

Hartree-Fock on a superconducting qubit quantum computer

The largest experimental quantum computation of chemistry to date, with double the qubits and 10X the number of gates than the previous record. We demonstrated new error mitigation techniques and modeled a chemical reaction mechanism for the first time.

Achieving Precision in Quantum Material Simulations

We outline a blueprint for achieving record levels of precision for the task of simulating quantum materials.

Demonstrating the Fundamentals of Quantum Error Correction

We outline in this paper how we use quantum repetition codes to demonstrate a new technique for reducing the amount of correlated errors in our physical qubits.
