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…
Competition for Survival and the Maximum Entropy Production Principle in Self-Organized Silver Particle Chains
Albert Han, Jiri Kataman-Kustwan, Alexey Bezryadin
The maximum entropy production (MEP) principle is a hypothetical law of physics which dictates that complex systems, far from equilibrium, evolve into an ordered dissipative struct…
Comparison of Two-Level System Microwave Losses in Pure Bulk Microcrystalline Nb2O5 and NbO2 Oxide Samples
Vishal Ganesan, Jiankun Zhang, Drew G. Wild +1
Losses from two-level systems (TLS) associated with amorphous oxides remain one of the primary limitations to the performance of superconducting qubits and microwave cavities. Niob…
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…
