Evanescent-wave Johnson Noise from Superconductors
Hruday Mallubhotla, Gustav Romare, Ilya Esterlis +3
We compute the evanescent-wave Johnson noise (EWJN) in the vacuum half-space above a superconductor, and the resulting relaxation time () of spin and charge qubits placed at n…
Voltage Activated Parametric Entangling Gates on Gatemons
Yinqi Chen, Konstantin N. Nesterov, Hugh Churchill +3
We describe the generation of entangling gates on superconductor-semiconductor hybrid qubits by ac voltage modulation of the Josephson energy. Our numerical simulations demonstrate…
Quasiparticle dynamics in epitaxial Al-InAs planar Josephson junctions
Bassel Heiba Elfeky, William M. Strickland, Jaewoo Lee +7
Quasiparticle (QP) effects play a significant role in the coherence and fidelity of superconducting quantum circuits. The Andreev bound states of high transparency Josephson juncti…
Fluxonium Qubits in a Flip-Chip Package
Aaron Somoroff, Patrick Truitt, Adam Weis +10
The strong anharmonicity and high coherence times inherent to fluxonium superconducting circuits are beneficial for quantum information processing. In addition to requiring high-qu…
Superconducting resonators with voltage-controlled frequency and nonlinearity
William M. Strickland, Bassel Heiba Elfeky, Joseph O'Connell Yuan +6
Voltage-tunable superconductor-semiconductor devices offer a unique platform to realize dynamic tunability in superconducting quantum circuits. By galvanically connecting a gated I…
Demonstration of the Two-Fluxonium Cross-Resonance Gate
Ebru Dogan, Dario Rosenstock, Loïck Le Guevel +7
The superconducting fluxonium qubit has a great potential for high-fidelity quantum gates with its long coherence times and strong anharmonicity at the half flux quantum sweet spot…
