Readout-Induced Leakage in Superconducting Circuits with Nonlinear Couplings
Sumeru Hazra, Wei Dai, Daniel K. Weiss +3
In superconducting circuits, drive-induced unwanted transitions limit the readout power, thereby constraining readout speed and fidelity. When such transitions excite the qubit int…
Characterization of drive-induced unwanted state transitions in superconducting circuits
W. Dai, S. Hazra, D. K. Weiss +11
Microwave drives are essential for implementing control and readout operations in superconducting quantum circuits. However, increasing the drive strength eventually leads to unwan…
Full characterization of measurement-induced transitions of a superconducting qubit
Thomas Connolly, Pavel D. Kurilovich, Vladislav D. Kurilovich +12
Repeated quantum non-demolition measurement is a cornerstone of quantum error correction protocols. In superconducting qubits, the speed of dispersive state readout can be enhanced…
Bias-preserving and error-detectable entangling operations in a superconducting dual-rail system
Nitish Mehta, James D. Teoh, Taewan Noh +69
For useful quantum computation, error-corrected machines are required that can dramatically reduce the inevitable errors experienced by physical qubits. While significant progress…
High-frequency readout free from transmon multi-excitation resonances
Pavel D. Kurilovich, Thomas Connolly, Charlotte G. L. Bøttcher +12
Quantum computation will rely on quantum error correction to counteract decoherence. Successfully implementing an error correction protocol requires the fidelity of qubit operation…
