Significance Here, we propose an architecture for quantum computing that applies the dual-rail encoding from quantum optics to a superconducting quantum circuit platform. In doing so, we not only benefit from the error detection properties of this encoding but also exploit the strong nonlinearities available in superconducting circuits, which enable gate-based quantum computation. While any useful quantum computer is expected to need quantum error correction, direct error detection allows us to know exactly where and when a qubit has an error, making error correction much easier. By designing the dual-rail qubits such that most of their errors can be detected, we believe that practical quantum error correction can already be achieved with the coherence times of today’s superconducting circuits.
