Helios achieves 98 qubits with single-qubit gate infidelity 2.5(1)×10^{-5}, two-qubit 7.9(2)×10^{-4}, and SPAM 4.8(6)×10^{-4}, enabling circuits beyond classical simulation.
A fluctuation-guided adaptive random compiler for Hamiltonian simulation dynamically adjusts term sampling probabilities according to state sensitivity to improve fidelity over fixed randomized methods.
Catalytic Quantum Error Correction recovers known target states from noisy copies with F > 0.96 using only eight copies by preserving coherent modes and applying a CPMG-Clifford-swap-test pipeline, bypassing magnitude thresholds of standard QEC.
New immanant and character-based filters reduce computational cost in bosonic randomized benchmarking while providing simple variance expressions and constant low variance for the character filter.
Derives symmetric Stinespring dilations and covariance constraints for Pauli channels and semigroups to enable explicit time-dependent constructions for quantum simulation.
