Nord Quantique Implements Post-Selected Stabilization to Suppress GKP Qubit SPAM Errors Below 0.1%

<p>Quantum hardware developer Nord Quantique has detailed an error-mitigation methodology that curtails State Preparation and Measurement (SPAM) error rates within single-mode bosonic grid-state qubits. Published as a preprint on arXiv ("Quantum error correction of a grid-state qubit with state prep
