Aperiodic Drives in Qubits Enable Moment-Selective Haar Statistics with Exponential Lifetime

The preprint introduces moment-selective temporal designs via aperiodic drives that achieve partial Haar statistics with long lifetimes under small detuning. Exact constructions for qubits show retained non-Haar moments at orders 3 and 6. A measurable finite-time signature is proposed to enable near-term tests.

Next steps require mapping the predicted finite-time signature onto existing superconducting or trapped-ion platforms. If confirmed, the approach could supply tunable statistical ensembles for quantum simulation and sensing protocols that need controlled deviation from randomness.

⚡ Prediction

Peng: Superconducting qubit experiments will detect the finite-time moment signature above noise floor within 18 months at detuning below 0.01.
