# Qubit reset experiment removes leakage during measurement without added time

_Published Wednesday, September 23, 2026 at 1:22 PM EDT · Science · Latest · Tier 2 — Notable_

Researchers demonstrated a method that returned superconducting qubits from an unusable state during measurement without extending the standard two-level readout process. Their leakage reduction unit removed 98.4% of leakage while maintaining 99.2% readout assignment fidelity, according to the reported experiments.

The method applies microwave drives to a qubit and its readout resonator at the same time. Paired with a neural network that interprets measurement results, it helped suppress logical errors in tests using up to nine qubits. The strongest reported error correction used three-level readout, whose assignment fidelity was 96.3%.
