Quantum Circuits: Funding, Investors & Team (Sep 2026)

Quantum Circuits, Inc. (QCI) is a privately owned company that was established in late 2015 with the primary objective of creating and selling the first practical and functional quantum computers using superconducting devices. The company also plans to commercialize various components, devices, and software that will aid in advancing research and facilitating the expansion of quantum computing. The name "Quantum circuits" is chosen to represent QCI's focus on the quantum circuit model for quantum computation and its reliance on superconducting Josephson junctions to function as qubits. QCI was founded by three experts in quantum devices and information processing - Michel Devoret, Luigi Frunzio, and Robert Schoelkopf, all of whom have a substantial history of innovation in the field. Their achievements include developing a "quantum bus" for qubit entanglement, implementing a quantum algorithm using solid-state devices, and demonstrating solid-state qubits with high levels of coherence.

About FundedIQ's Quantum Circuits Funding Data

FundedIQ tracks announced funding rounds and refreshes this profile every week. Round dates, stages and amounts are normalised to a single format, converted to US dollars, and de-duplicated: two records of the same round announced days apart are merged, and two genuinely different rounds are kept apart on the amounts they disclose. Amounts shown are the disclosed figures only — a round announced without a number is listed and excluded from the total rather than estimated.

Employee counts are reported bands, not exact headcounts. Founder and executive names carry the job title on record. Anything we do not hold for Quantum Circuits is left off this page rather than filled in.
