Elimination of Flux Trapping in Superconducting Circuits in Ambient Magnetic Fields
Rohan T. Kapur, Alex Wynn, Sergey K. Tolpygo +10
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…
Quantum Frequency Mixing using an N- Diamond Microscope
Samuel J. Karlson, Pauli Kehayias, Jennifer M. Schloss +6
Wide-field magnetic microscopy using nitrogen-vacancy (NV) centers in diamond can yield high-quality magnetic images of DC and AC magnetic fields. The unique combination of micron-…
Room temperature optomechanical squeezing
Nancy Aggarwal, Torrey Cullen, Jonathan Cripe +7
The radiation-pressure driven interaction of a coherent light field with a mechanical oscillator induces correlations between the amplitude and phase quadratures of the light. Thes…
Observation of a room-temperature oscillator's motion dominated by quantum fluctuations over a broad audio-frequency band
Jonathan Cripe, Nancy Aggarwal, Robert Lanza +7
We report on the broadband measurement of quantum radiation pressure noise (QRPN) in an optomechanical cavity at room temperature over a broad range of frequencies relevant to grav…
