Quantum Circuits announced it has secured a final Series B investment round of more than $60 million, providing additional capital support as the company prepares to commercialize its quantum systems with an industry first - error detection built into a more powerful qubit for scalable, higher-fidelity computing.

The investment is led by ARCH Venture Partners, F-Prime Capital, Sequoia Capital, and Hither Creek Ventures. The Series B round also includes investment from Canaan Partners, Fitz Gate Ventures, In-Q-Tel (IQT), Osage University Partners, Connecticut Innovations, Tao Capital Partners, and Tribeca Venture Partners.

Quantum Circuits is founded by quantum physicists, including leading quantum expert and Yale Professor Rob Schoelkopf. The company is a leader in the development of quantum computers designed to scale. Quantum Circuits' innovative architecture integrates high-fidelity qubits with intrinsic error detection and handling. High-fidelity error detection is a key component to reducing the number of physical qubits necessary to build a useful quantum computer, thus accelerating the timeline to fault-tolerant quantum computing and real-world applications. Quantum Circuits' team includes pioneers in the development of superconducting quantum science and circuit quantum electrodynamics.
