Working paper tests the fidelity of a spectral error model in a superconducting processor, suggesting important implications for quantum computing.
We pre-register and test a spectral-error-mitigation prediction for the two-qubit gate fidelity of Quantum Inspire's Tuna-9 9-qubit transmon processor and execute it in four cryptographically timestamped stages. Maturity: Working Paper. Target venue: Physical Review X Quantum (PRX Quantum); arXiv quant-ph. Part of The Latent research program. Related papers in this program: Phy Quantum Usrt.
