Combinatorial Optimization with Physics-Inspired Graph Neural Networks

Combinatorial optimization problems, such as the traveling salesman problem where we are looking for an optimal path with a discrete number of variables, are pervasive across science and industry. Practical (and yet notoriously challenging) applications can be found in virtually every industry, such as transportation and logistics, telecommunications, and finance. For example, optimization algorithms help […]

Amazon Braket launches Lucy, a new quantum processor from Oxford Quantum Circuits and expands to the Europe (London) Region

Since launch, Amazon Braket has been committed to providing customers with a single access point to different quantum hardware choices, allowing them to experiment and innovate with multiple quantum processing units (QPUs) through the same interface. Today we announce the general availability of the first publicly available QPU from Oxford Quantum Circuits (OQC). The device, […]

Updates from re:Invent 2021

With so much happening at the annual re:Invent conference, it would be easy to miss some of the updates in AWS Quantum Technologies. In this post we summarize four recent announcements: a new feature that helps customers run hybrid quantum-classical algorithms more easily and with better performance, two new quantum processing units (QPUs) coming to […]

Announcing the opening of the AWS Center for Quantum Computing

What if by harnessing the properties of quantum mechanics we could model and simulate the behavior of matter at its most fundamental level, down to how molecules interact? The machine that would make that possible would be transformative, changing what we know about science and how we probe nature for answers. Quantum computers have the […]

Low-overhead quantum computing with Gottesman-Kitaev-Preskill qubits

Introduction This post summarizes a research paper from the AWS Center for Quantum Computing that proposes a direction to implement fault-tolerant quantum computers with minimal hardware overhead. This research shows that by concatenating the surface code with Gottesman, Kitaev, and Preskill (GKP) qubits, it is theoretically possible to achieve a logical error rate of 10-8 […]

Designing a fault-tolerant quantum computer based on Schrödinger-cat qubits

At the AWS Center for Quantum Computing, we are doing scientific research and development on quantum computing algorithms and hardware. This post summarizes findings from our first architecture paper that describes a theoretical blueprint for a fault-tolerant quantum computer that features a novel approach to quantum error correction (QEC). Fair warning, this post dives somewhat […]
