Superconductor digital electronics and quantum computing with superconducting qubits are promising next-generation computing technologies. When cooled down or operated in the prese…
Mitigation of Magnetic Flux Trapping in Superconducting Electronics Using Moats
Rohan T. Kapur, Sergey K. Tolpygo, Alex Wynn +7
Magnetic flux (vortex) trapping remains a major obstacle to very large scale integration in superconducting electronics. Moats -- etched regions in circuit layers placed in ground…
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…
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…
