Bifluxon: Fluxon-Parity-Protected Superconducting Qubit
Konstantin Kalashnikov, Wen Ting Hsieh, Wenyuan Zhang +6
We have developed and characterized a symmetry-protected superconducting qubit that offers simultaneous exponential suppression of energy decay from charge and flux noise, and deph…
Granular Aluminum Meandered Superinductors for Quantum Circuits
Plamen Kamenov, Wen-Sen Lu, Konstantin Kalashnikov +3
We have designed superinductors made of strongly disordered superconductors for implementation in "hybrid" superconducting quantum circuits. The superinductors have been fabricated…
Josephson Ladders as a Model System for 1D Quantum Phase Transitions
M. T. Bell, B. Doucot, M. E. Gershenson +2
We propose a novel platform for the study of quantum phase transitions in one dimension (1D QPT). The system consists of a specially designed chain of asymmetric SQUIDs; each SQUID…
Spectroscopic Evidence of the Aharonov-Casher effect in a Cooper Pair Box
M. T. Bell, W. Zhang, L. B. Ioffe +1
We have observed the effect of the Aharonov-Casher (AC) interference on the spectrum of a superconducting system containing a symmetric Cooper pair box (CPB) and a large inductance…
Protected Josephson Rhombi Chains
Matthew T. Bell, Joshua Paramanandam, Lev B. Ioffe +1
We have studied the low-energy excitations in a minimalistic protected Josephson circuit which contains two basic elements (rhombi) characterized by the periodicity of the Jose…
Quantum Superinductor with Tunable Non-Linearity
M. T. Bell, I. A. Sadovskyy, L. B. Ioffe +2
We report on the realization of a superinductor, a dissipationless element whose microwave impedance greatly exceeds the resistance quantum. The design of the superinductor, implem…
