Symmetry of the critical current function in superconducting nanodevices
Ziqi Zhao, Cliff Sun, Ci-You Huang +3
We study a variety of nano-scale superconducting devices containing more than one weak link. Even in devices with multiple weak links the IB symmetry is usually obeyed, which means…
A Dayem Loop Qubit Based on Interfering Superconducting Nanowires
Cliff Sun, Alexey Bezryadin
We propose a qubit design based on two parallel superconducting nanowires (i.e., a "Dayem loop qubit"). The inclusion of two nanowires instead of one leads to the Little-Parks effe…
Perfect Superconducting Diode and Supercurrent Range Controller
Cliff Sun, Ziqi Zhao, Alexey Bezryadin
Diodes have a nonreciprocal voltage versus current relationship, produced by breaking the space and time reversal symmetry. However, developing high-end superconducting computers r…
Multiple-Nanowire Superconducting Quantum Interference Devices: Critical Currents, Symmetries, and Vorticity Stability Regions
Cliff Sun, Alexey Bezryadin
An ordinary superconducting quantum interference device (SQUID) contains two weak links connected in parallel. We model a multiple-wire SQUID (MW-SQUID), generalized in two ways. F…
