Evidence for unexpectedly low quasiparticle generation rates across Josephson junctions of driven superconducting qubits
Byoung-moo Ann, Sang-Jun Choi, Hee Chul Park +6
Recent studies find that even drives far below the superconducting gap frequency may cause drive-induced quasiparticle generation (QPG) across Josephson junctions (JJs) of supercon…
Entangling interactions between artificial atoms mediated by a multimode left-handed superconducting ring resonator
T. McBroom-Carroll, A. Schlabes, X. Xu +6
Superconducting metamaterial transmission lines implemented with lumped circuit elements can exhibit left-handed dispersion, where the group and phase velocity have opposite sign,…
Quasiparticle Poisoning of Superconducting Qubits from Resonant Absorption of Pair-breaking Photons
Chuan-Hong Liu, David C. Harrison, Shravan Patel +8
The ideal superconductor provides a pristine environment for the delicate states of a quantum computer: because there is an energy gap to excitations, there are no spurious modes w…
Phonon downconversion to suppress correlated errors in superconducting qubits
V. Iaia, J. Ku, A. Ballard +6
Quantum error correction can preserve quantum information in the presence of local errors, but correlated errors are fatal. For superconducting qubits, high-energy particle impacts…
Suppression of Unwanted Interactions in a Hybrid Two-Qubit System
Jaseung Ku, Xuexin Xu, Markus Brink +4
Mitigating crosstalk errors, whether classical or quantum mechanical, is critically important for achieving high-fidelity entangling gates in multi-qubit circuits. For weakly anhar…
Digital coherent control of a superconducting qubit
Edward Leonard, Matthew A. Beck, JJ Nelson +15
High-fidelity gate operations are essential to the realization of a fault-tolerant quantum computer. In addition, the physical resources required to implement gates must scale effi…
