Leakage Error Analysis in Isolated Superconductor Multi-State Qubit Transmon

https://doi.org/10.2025/b8rk4570Abstract
In this letter, experimental results of an isolated superconductor qubit transmon are presented. The carrier frequency is scanned within a wide bandwidth covering resonances with higher states and then the leakage probabilities are measure by sensitive measuring protocols. The experimental data were compared to typical predictions to determine the active leakage rates and dangerous resonance bandwidth. This work may provide a quantum understanding and base for one of the important error sources in the digital quantum computing to achieve much more reliable systems.
