Calibration of Drive Non-Linearity for Arbitrary-Angle Single-Qubit Gates Using Error Amplification
Stefania Lazăr, Quentin Ficheux, Johannes Herrmann +12
The ability to execute high-fidelity operations is crucial to scaling up quantum devices to large numbers of qubits. However, signal distortions originating from non-linear compone…
Frequency Up-Conversion Schemes for Controlling Superconducting Qubits
Johannes Herrmann, Christoph Hellings, Stefania Lazar +8
High-fidelity control of superconducting qubits requires the generation of microwave-frequency pulses precisely tailored on nanosecond timescales. These pulses are most commonly sy…
Magnetic imaging of superconducting qubit devices with scanning SQUID-on-tip
E. Marchiori, L. Ceccarelli, N. Rossi +6
We use a scanning superconducting quantum interference device (SQUID) to image the magnetic flux produced by a superconducting device designed for quantum computing. The nanometer-…
