Link between supercurrent diode and anomalous Josephson effect revealed by gate-controlled interferometry
Simon Reinhardt, Tim Ascherl, Andreas Costa +9
In Josephson diodes the asymmetry between positive and negative current branch of the current-phase relation leads to a polarity-dependent critical current and Josephson inductance…
Multimode Ultrastrong Coupling in Three-Dimensional Photonic-Crystal Cavities
Fuyang Tay, Ali Mojibpour, Stephen Sanders +8
Recent theoretical studies have highlighted the role of spatially varying cavity electromagnetic fields in exploring novel cavity quantum electrodynamics (cQED) phenomena, such as…
Real-time two-axis control of a spin qubit
Fabrizio Berritta, Torbjørn Rasmussen, Jan A. Krzywda +9
Optimal control of qubits requires the ability to adapt continuously to their ever-changing environment. We demonstrate a real-time control protocol for a two-electron singlet-trip…
Josephson diode effect derived from short-range coherent coupling
Sadashige Matsuo, Takaya Imoto, Tomohiro Yokoyama +6
Superconducting devices with broken time-reversal and spatial-inversion symmetries can exhibit novel superconducting phenomena. The observation of superconducting diode effects, wh…
Engineering of anomalous Josephson effect in coherently coupled Josephson junctions
Sadashige Matsuo, Takaya Imoto, Tomohiro Yokoyama +6
A Josephson junction (JJ) is a key device in the development of superconducting circuits, wherein a supercurrent in the JJ is controlled by the phase difference between the two sup…
An rf Quantum Capacitance Parametric Amplifier
A. El Kass, C. T. Jin, J. D. Watson +4
We demonstrate a radio-frequency parametric amplifier that exploits the gate-tunable quantum capacitance of an ultra high mobility two dimensional electron gas (2DEG) in a GaAs het…
