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…
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…
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…
