A gate-tunable, field-compatible fluxonium
Marta Pita-Vidal, Arno Bargerbos, Chung-Kai Yang +7
Circuit quantum electrodynamics, where photons are coherently coupled to artificial atoms built with superconducting circuits, has enabled the investigation and control of macrosco…

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…
