Quantum Circuits launches dual-rail qubits for improved error correction in quantum computing

A new qubit technology called dual-rail qubits is now available to customers through a cloud service from startup Quantum Circuits. This technology simplifies error detection, making error correction in quantum computing more efficient. Dual-rail qubits are based on existing transmon hardware, linking two systems to control the movement of microwave photons. This setup allows for better management of quantum information, enhancing the reliability of quantum computing. While Amazon has been testing dual-rail qubits, Quantum Circuits is the first to offer them publicly. This development marks a significant step in the evolution of quantum computing technology.
