Stability. Repeatability. Consistency.
Quantum Circuits Inc. (QCI) built fault-tolerant quantum computers based on superconducting Dual-Rail Cavity Qubits with built-in error detection. QCI pioneered the industry's first dual-rail qubit with quantum error detection (QED), real-time control flow (RTCF), and error detection handling enabling high-fidelity algorithm execution. Founded at Yale University in 2015 by applied physicist Robert Schoelkopf, QCI was acquired by D-Wave Quantum Inc. in January 2026 for $550 million, forming the world's first dual-platform quantum computing company.
