Sandia and Quantinuum Introduce Logical Gate Set Tomography to Map Fault-Tolerant Qubit Noise
TL;DRNew method maps errors in quantum computers' logical qubits with unprecedented detail.
Why it matters: Better error measurement accelerates practical, fault-tolerant quantum computing development.
Researchers from Sandia National Laboratories and Quantinuum have introduced "Logical GST," a protocol that provides the first self-consistent, full tomographic reconstruction of a universal single-qubit logical gate set. This was implemented on a single logical qubit encoded in…
