Calibrating Magnetic Flux Control in Superconducting Circuits by Compensating Distortions on Time Scales from Nanoseconds up to Tens of Microseconds
Christoph Hellings, Nathan Lacroix, Ants Remm +8
Fast tuning of the transition frequency of superconducting qubits using magnetic flux is essential, for example, for realizing high-fidelity two-qubit gates with low leakage or for…
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-…
Realizing Repeated Quantum Error Correction in a Distance-Three Surface Code
Sebastian Krinner, Nathan Lacroix, Ants Remm +13
Quantum computers hold the promise of solving computational problems which are intractable using conventional methods. For fault-tolerant operation quantum computers must correct e…
Realizing Quantum Convolutional Neural Networks on a Superconducting Quantum Processor to Recognize Quantum Phases
Johannes Herrmann, Sergi Masot Llima, Ants Remm +15
Quantum computing crucially relies on the ability to efficiently characterize the quantum states output by quantum hardware. Conventional methods which probe these states through d…
