Qubit that makes most errors obvious now available to customers

Quantum Circuits, a new startup, has introduced the first publicly available dual-rail qubit system. This technology enhances photon loss error detection, potentially improving error correction efficiency. Dual-rail qubits utilize two linked resonators, facilitating easier detection of common errors. The initial 8-qubit system is designed to help users explore this new architecture for improved error correction. This development reflects a trend among quantum startups to prioritize error reduction over simply increasing qubit counts.
