IBM Quantum

IBM Quantum Services provides access to more than 20 currently available quantum systems (known as backends). IBM’s quantum processors are made up of superconducting transmon qubits, and users can utilize these systems via the universal, gate-based, circuit model of quantum computation. Additionally, users have access to 5 different types of simulators, simulating from 32 up to 5000 qubits to represent different aspects of the quantum backends.

Rigetti currently offers access to their systems via their Quantum Cloud Services (QCS). With QCS, Rigetti’s quantum processors (QPUs) are tightly integrated with classical computing infrastructure and made available to you over the cloud. Rigetti also provides users with quantum computing example algorithms for optimization, quantum system profiling, and other applications.

A list of available Rigetti systems/QPUs, along with their performance statistics, can be found on the Rigetti Systems Page.
