Since late 2019, Amazon Braket has been in private preview. However, Amazon AWS recently announced its general availability. Customers can purchase quantum computing services directly from the Amazon Braket platform.
Amazon named the service after a standard quantum notation called Bra–ket that was created in the late 1930s by Paul Dirac, a famous theoretical physicist.
Braket is a fully managed AWS service that provides a mostly technology-agnostic environment. It offers customers the capability to design, develop, test, and run their quantum algorithms. Braket also offers simulated quantum computers that use Amazon EC2 computing resources and can simulate up to 34 qubits for testing and troubleshooting algorithms.
For now, the service is currently available in the following AWS regions: US East (N. Virginia), US West (N. California), and US West (Oregon).
Braket offers a choice of three different quantum hardware technologies.
