Amazon Web Services (AWS) is expanding its quantum computing partnership with QuEra.

The companies announced an expanded strategic collaboration this week to bring Libra, the company's first fault-tolerant quantum computer capable of tackling scientifically relevant problems, to Amazon’s Braket quantum cloud platform.

By 2028, Amazon will make QuEra’s Libra, a “Megaquop-scale” device, capable of executing one million quantum operations over hundreds of logical qubits, available to its customers.

“This is a very special moment - for the first time, a dream of realizing useful, fault-tolerant quantum computers is in our direct line of sight. Designed to enable quantum computation at an unprecedented scale, these systems should realize truly unique applications. We are proud to significantly expand our collaboration with AWS to bring these unique capabilities to the broader community of scientific users,” said Prof. Mikhail Lukin, chief science officer, QuEra Computing.

Eric Kessler, general manager for Amazon Braket, at AWS, added: "We believe fault-tolerant quantum computing will become a foundational part of how customers solve their hardest computational problems on AWS. QuEra's technology has demonstrated a clear path to that future. By bringing these capabilities to customers through Amazon Braket, they can combine QuEra's fault-tolerant quantum processors with the scalable AWS HPC and AI services they already rely on."

Braket launched in the US in 2020, allowing customers to book time on quantum computers from a number of different hardware providers. The quantum systems are not housed in AWS data centers; instead, they are hosted by their respective providers and connect to AWS’ cloud via APIs.

As well as offering access to its own quantum simulators, quantum companies with systems available through Braket include IonQ, IQM, Rigetti, AQT, and QuEra.

Founded in 2019 by Harvard and MIT alumni, Boston-based QuEra Computing Inc. offers neutral-atom-based quantum computing, which is based on programmable arrays of neutral Rubidium atoms, trapped in a vacuum by tightly focused laser beams.

The company operates a lab and data center near the Charles River in Boston and offers on-premise quantum systems as well as access to quantum hardware through its own cloud and Amazon Web Services.

The company put its 256-qubit Aquila system on Braket back in 2022.

QuEra has installed on-premise quantum computers at Japan’s National Institute of Advanced Industrial Science and Technology and the UK’s National Quantum Computing Centre.

Investors in QuEra include Nvidia, Google, SoftBank, Valor Equity Partners, QVT Family Office, and Safar Partners.

Amazon is also developing its own quantum hardware, but is yet to make its Ocelot chips publicly available. The company has its own quantum computing center in California, with the facility set to host the first AWS-made systems due to go live on its Braket service.
