Fault-tolerant operation of a logical qubit in a diamond quantum processor.

ABSTRACT: Solid-state spin qubits is a promising platform for quantum computation and quantum networks^1,2. Recent experiments have demonstrated high-quality control over multi-qubit systems^3-8, elementary quantum algorithms^8-11 and non-fault-tolerant error correction^12-14. Large-scale systems will require using error-corrected logical qubits that are operated fault tolerantly, so that reliable computation becomes possible despite noisy operations^15-18. Overcoming imperfections in this way remains an important outstanding challenge for quantum science^15,19-27. Here, we demonstrate fault-tolerant operations on a logical qubit using spin qubits in diamond. Our approach is based on the five-qubit code with a recently discovered flag proto
