Quantum Circuits Inc
About
Quantum Circuits Inc (QCI) is a Yale University spinout founded in 2015 by Prof. Rob Schoelkopf, developing superconducting quantum computers with dual-rail cavity qubits (DRQs) requiring 10x fewer physical qubits per logical qubit.
August 2024: Raised $60M Series B led by ARCH Venture Partners, F-Prime Capital, Sequoia Capital, Hither Creek Ventures (total funding: $125M). May 2024: Additional $26.5M from Sequoia. November 2024: Announced Aqumen Seeker QPU - industry's first 8-qubit processor with integrated hardware error detection on every qubit.
2025: Achieved ~0.1% error per CZ gate - among best in superconducting systems. Technology features built-in error detection without additional overhead. Roadmap targets fault-tolerant quantum computing through native error correction.
