Offset Charge Dependence of Measurement-Induced Transitions in Transmons
Mathieu Féchant, Marie Frédérique Dumas, Denis Bénâtre +9
A key challenge in achieving scalable fault tolerance in superconducting quantum processors is readout fidelity, which lags behind one- and two-qubit gate fidelity. A major limitat…
