A simple formula for the average gate fidelity of a quantum dynamical operation
read the original abstract
This note presents a simple formula for the average fidelity between a unitary quantum gate and a general quantum operation on a qudit, generalizing the formula for qubits found by Bowdrey et al [Phys. Lett. A 294, 258 (2002)]. This formula may be useful for experimental determination of average gate fidelity. We also give a simplified proof of a formula due to Horodecki et al [Phys. Rev. A 60, 1888 (1999)], connecting average gate fidelity to entanglement fidelity.

Impact of gate-voltage noise on silicon spin-qubit variational quantum eigensolvers
A hardware-algorithm co-simulation identifies noise regimes where silicon spin-qubit VQE can still reach chemically accurate H2 ground-state energies, showing exchange gates are far more sensitive than single-qubit rotations.
