Scaling and logic in the colour code on a superconducting quantum processor.

ABSTRACT: Quantum error correction^1-4 is essential for bridging the gap between the error rates of physical devices and the extremely low error rates required for quantum algorithms. Recent error-correction demonstrations on superconducting processors^5-8 have focused primarily on the surface code⁹, which offers a high error threshold but poses limitations for logical operations. The colour code¹⁰ enables more efficient logic, but it requires more complex stabilizer measurements and decoding. Measuring these stabilizers in planar architectures such as superconducting qubits is challenging, and realizations of colour codes^11-19 have not addressed performance scaling with code size on any platform. Here we present a comprehensive demonstration of t
