Junction-Intrinsic Dissipation in Hybrid Superconductor-Semiconductor Gatemon Qubits
Zhenhai Sun, David Feldstein-Bofill, Ksenia Shagalov +10
Superconducting transmon qubits based on hybrid superconductor-semiconductor Josephson junctions (gatemons) offer gate tunability, but their relaxation times remain well below thos…
Localized quasiparticles in a fluxonium with quasi-two-dimensional amorphous kinetic inductors
Trevyn F. Q. Larson, Sarah Garcia Jones, Tamás Kalmár +10
Disordered superconducting materials with high kinetic inductance are an important resource to generate nonlinearity in quantum circuits and create high-impedance environments. In…
Nonreciprocal devices based on voltage-tunable junctions
Catherine Leroux, Adrian Parra-Rodriguez, Ross Shillito +6
We propose to couple the flux degree of freedom of one mode with the charge degree of freedom of a second mode in a hybrid superconducting-semiconducting architecture. Nonreciproci…
Moving beyond the transmon: Noise-protected superconducting quantum circuits
András Gyenis, Agustin Di Paolo, Jens Koch +3
Artificial atoms realized by superconducting circuits offer unique opportunities to store and process quantum information with high fidelity. Among them, implementations of circuit…
Floquet-engineered enhancement of coherence times in a driven fluxonium qubit
Pranav S. Mundada, András Gyenis, Ziwen Huang +2
We use the quasienergy structure that emerges when a fluxonium superconducting circuit is driven periodically to encode quantum information with dynamically induced flux-insensitiv…
Engineering Dynamical Sweet Spots to Protect Qubits from 1/ Noise
Ziwen Huang, Pranav S. Mundada, András Gyenis +3
Protecting superconducting qubits from low-frequency noise is essential for advancing superconducting quantum computation. Based on the application of a periodic drive field, we de…
