Q-Profile: Profiling Tool for Quantum Control Stacks applied to the Quantum Approximate Optimization Algorithm
Koen J. Mesman, Francesco Battistel, Edgar Reehuis +5
Scaling up the number of qubits and speeding up the execution of quantum algorithms are important steps towards reaching quantum advantage. This poses heavy demands particularly on…
Time-domain characterization and correction of on-chip distortion of control pulses in a quantum processor
M. A. Rol, L. Ciorciaro, F. K. Malinowski +7
We introduce Cryoscope, a method for sampling on-chip baseband pulses used to dynamically control qubit frequency in a quantum processor. We specifically use Cryoscope to measure t…
Protecting quantum entanglement from leakage and qubit errors via repetitive parity measurements
C. C. Bultink, T. E. O'Brien, R. Vollmer +9
Protecting quantum information from errors is essential for large-scale quantum computation. Quantum error correction (QEC) encodes information in entangled states of many qubits,…
A fast, low-leakage, high-fidelity two-qubit gate for a programmable superconducting quantum computer
M. A. Rol, F. Battistel, F. K. Malinowski +8
A common approach to realize conditional-phase (CZ) gates in transmon qubits relies on flux control of the qubit frequency to make computational states interact with non-computatio…
Error Mitigation by Symmetry Verification on a Variational Quantum Eigensolver
R. Sagastizabal, X. Bonet-Monroig, M. Singh +11
Variational quantum eigensolvers offer a small-scale testbed to demonstrate the performance of error mitigation techniques with low experimental overhead. We present successful err…
General method for extracting the quantum efficiency of dispersive qubit readout in circuit QED
C. C. Bultink, B. Tarasinski, N. Haandbaek +5
We present and demonstrate a general three-step method for extracting the quantum efficiency of dispersive qubit readout in circuit QED. We use active depletion of post-measurement…
