Demonstration of Superconductor Shift Registers with Energy Dissipation Below Landauer's Thermodynamic Limit
Sergey K. Tolpygo, Evan B. Golden, Vasili K. Semenov
We study energy dissipation and propagation of information encoded by Josephson vortices in two types of circular shift register: a) a uniform register composed of sections of disc…
Magnetic flux imaging in a 3D superconductor integrated circuit
Tong Ren, Andres Glatz, Boldizsar Jankó +3
We report on imaging magnetic flux distributions in a multilayered superconductor integrated circuit which emerge during magnetization and after field cooling of the circuit in the…
Fabrication and Properties of NbN/NbNx/NbN and Nb/NbNx/Nb Josephson Junctions
Sergey K. Tolpygo, Ravi Rastogi, David Kim +3
Increasing integration scale of superconductor electronics (SCE) requires employing kinetic inductors and self-shunted Josephson junctions (JJs) for miniaturizing inductors and JJs…
Flux-trapping characterization for superconducting electronics using a cryogenic widefield N- diamond microscope
Rohan T. Kapur, Pauli Kehayias, Sergey K. Tolpygo +12
Magnetic flux trapping is a significant hurdle limiting the reliability and scalability of superconducting electronics, yet tools for imaging flux vortices remain slow or insensiti…
