Evidence of dual Shapiro steps in a Josephson junctions array
Nicolò Crescini, Samuel Cailleaux, Wiebke Guichard +4
The modern primary voltage standard is based on the AC Josephson effect and the ensuing Shapiro steps, where a microwave tone applied to a Josephson junction yields a constant volt…
Optical Direct Write of Dolan--Niemeyer-Bridge Junctions for Transmon Qubits
J. T. Monroe, D. Kowsari, K. Zheng +4
We characterize highly coherent transmon qubits fabricated with a direct-write photolithography system. Multi-layer evaporation and oxidation allows us to change the critical curre…
Understanding the saturation power of Josephson Parametric Amplifiers made from SQUIDs arrays
Luca Planat, Remy Dassonneville, Javier Puertas Martinez +7
We report on the implementation and detailed modelling of a Josephson Parametric Amplifier (JPA) made from an array of eighty Superconducting QUantum Interference Devices (SQUIDs),…
Quantum feedback control of a superconducting qubit: Persistent Rabi oscillations
R. Vijay, C. Macklin, D. H. Slichter +5
The act of measurement bridges the quantum and classical worlds by projecting a superposition of possible states into a single, albeit probabilistic, outcome. The time-scale of thi…
Single crystal silicon capacitors with low microwave loss in the single photon regime
S. Weber, K. W. Murch, D. H. Slichter +2
We have fabricated superconducting microwave resonators in a lumped element geometry using single crystal silicon dielectric parallel plate capacitors with C >2 pF. Aluminum device…
