Quantum Circuits Company is a company that is aiming to develop, manufacture, and sell the first practical and useful quantum computer using superconducting qubits. It is based in New Haven, Connecticut and founded in 2015 by Robert J. Schoelkopf, Michel Devoret, Luigi Frunzio and Brian W. Pusch.

Quantum Circuits, Inc. (QCI) is a company that is aiming to develop, manufacture, and sell the first practical and useful quantum computer based on superconducting devices. QCI was founded in late 2015, by three scientists at Yale University's Applied Physics Department Luigi Frunzio, Michel Devoret, and Robert Schoelkopf alongside Brian Pusch, a technology startup veteran and the founder of New York law firm Pusch & Gal. The company is based in New Haven, Connecticut.

In 2017, QCI closed a Series A funding round of $18M led by Canaan and Sequoia Capital with participation from Osage University Partners, Tribeca Ventures, and Seed round investors Fitz Gate Ventures.

QCI is developing quantum computing hardware using superconducting qubits in a modular, robust, and scalable architecture. QCI will commercialize it's components, devices, and software to accelerate basic research and enable the scaling of quantum computing.

In November 2019, QCI announced a partnership with Microsoft on it's Azure Quantum initiative, a full-stack, open cloud ecosystem. The partnership will enable customers to run programs on QCI's prototype superconducting quantum computer while taking advantage of Microsoft’s extensive quantum software, development tools, and other resources.
