D-Wave Publishes Research on Dual-Rail Qubit Gate for Quantum Error Correction
D-Wave published research detailing a dual-rail qubit gate operation on its superconducting processor, aimed at enabling quantum error correction. The dual-rail encoding uses two physical qubits to represent a logical qubit, allowing for error detection. This work represents a move beyond annealing into gate-based fault-tolerant quantum computing.

D-Wave could demonstrate a logical qubit with error detection within two years, integrating the dual-rail gate into a small-scale device.
D-Wave has extensive experience fabricating and controlling superconducting qubits; dual-rail encoding is a relatively straightforward error detection scheme that requires only single-qubit gates and a two-qubit gate, both demonstrated in this work.
