High-quality and field resilient microwave resonators on Ge/SiGe quantum well heterostructures
Luigi Ruggiero, Carlo Ciacca, Pauline Drexler +5
Superconducting resonators integrated with Ge quantum wells (QWs) offer a promising platform for hybrid quantum devices. Yet, in the most common heterostructure architectures, they…

Radio-Frequency Detection of Fabry-Pérot Interference and Quantum Capacitance in Long-Channel Three-Dimensional Dirac Semimetal Cd3As2 Nanowires
Sung Jin An, Jisu Kim, Myung-Chul Jung +10
We demonstrate phase-coherent transport in suspended long-channel Cd3As2 nanowire devices using both direct current (DC) transport and radio-frequency (RF) reflectometry measuremen…

Entangled Photon-Pair Emission in Waveguide Circuit QED from a Cooper Pair Splitter
Michele Governale, Christian Schönenberger, Pasquale Scarlino +1
As a waveguide circuit QED architecture, we investigate theoretically the single-photon pair emission of a Cooper pair splitter composed of two double quantum dots, each coupled to…
