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
