Rigetti Computing

Rigetti Computing, a NASDAQ-listed superconducting qubit specialist, powers its 84-qubit Aspen-M-3 chip with an in-house quantum chip fabrication facility, a unique asset that gives it a 40% faster chip iteration cycle than the industry average. Its Quantum Cloud Services platform enables businesses to access gate-based quantum computing directly from the cloud, with a reported 99.5% uptime for enterprise workloads. This integrated approach makes it more accessible than #8 Microsoft Azure Quantum's hardware-agnostic strategy, which relies on third-party partners for qubit execution.
