Characterization of Radiation-Induced Errors in Superconducting Qubits Protected with Various Gap-Engineering Strategies
H. Douglas Pinckney, Thomas McJunkin, Alan W. Hunt +26
Impacts from high-energy particles cause correlated errors in superconducting qubits by increasing the quasiparticle density in the vicinity of the Josephson junctions (JJs). Such…
Characterization and Comparison of Energy Relaxation in Fluxonium Qubits
Kate Azar, Lamia Ateshian, Mallika T. Randeria +19
Fluxonium superconducting qubits have demonstrated long coherence times and high single- and two-qubit gate fidelities, making them a favorable building block for superconducting q…
Dephasing in Fluxonium Qubits from Coherent Quantum Phase Slips
Mallika T. Randeria, Thomas M. Hazard, Agustin Di Paolo +12
Phase slips occur across all Josephson junctions (JJs) at a rate that increases with the impedance of the junction. In superconducting qubits composed of JJ-array superinductors --…
Superconductivity and strong interactions in a tunable moiré quasiperiodic crystal
Aviram Uri, Sergio C. de la Barrera, Mallika T. Randeria +10
Electronic states in quasiperiodic crystals generally preclude a Bloch description, rendering them simultaneously fascinating and enigmatic. Owing to their complexity and relative…
Tuning interactions between spins in a superconductor
Hao Ding, Yuwen Hu, Mallika T. Randeria +5
Novel many-body and topological electronic phases can be created in assemblies of interacting spins coupled to a superconductor, such as one-dimensional topological superconductors…
Highly Tunable Junctions and Nonlocal Josephson Effect in Magic Angle Graphene Tunneling Devices
Daniel Rodan-Legrain, Yuan Cao, Jeong Min Park +5
Magic-angle twisted bilayer graphene (MATBG) has recently emerged as a highly tunable two-dimensional (2D) material platform exhibiting a wide range of phases, such as metal, insul…
