Quantum Circuits, Inc. is a quantum computing hardware company (a Yale University spinout) building superconducting quantum systems with built-in error detection. Its dual-rail cavity qubits pair Quantum Error Detection (QED), Real-Time Control Flow (RTCF), and Error Detection Handling (EDH), and its Aqumen Seeker QPU (introduced November 2024) targets stable, repeatable, fault-tolerant quantum computation. The company engages early users through a Strategic Quantum Release (SQR) program that includes a simulator and access to Aqumen Seeker systems, rather than a public self-serve API. Surfaced as a portfolio company of Canaan Partners and added to the API Evangelist network.
