Microwave radiometry of a quantum-critical, hybrid Josephson array
Kristen W. Léonard, Anton V. Bubis, Melissa Mikalsen +6
Arrays of Josephson junctions can be tuned through anomalous metallic, quantum-critical, and insulating regimes. We introduce a new experimental probe, capturing microwave radiatio…
Enhanced superconducting diode effect in hybrid Josephson junctions
Peng Yu, Han Fu, William F. Schiela +7
The superconducting diode effect (SDE) has recently been observed in various systems, sparking interest in novel superconducting devices and offering a new platform to probe intrin…
Bias-preserving and error-detectable entangling operations in a superconducting dual-rail system
Nitish Mehta, James D. Teoh, Taewan Noh +69
For useful quantum computation, error-corrected machines are required that can dramatically reduce the inevitable errors experienced by physical qubits. While significant progress…
Gate tunable enhancement of supercurrent in hybrid planar Josephson junctions
Peng Yu, Han Fu, William F. Schiela +6
Planar Josephson junctions (JJs) have emerged as a promising platform for the realization of topological superconductivity and Majorana zero modes. To obtain robust quasi one-dimen…
Gatemonium: A Voltage-Tunable Fluxonium
William M. Strickland, Bassel Heiba Elfeky, Lukas Baker +6
We present a new style of fluxonium qubit, gatemonium, based on an all superconductorsemiconductor hybrid platform. The linear inductance is achieved using six hundred planar Al-In…
