Giant nonlinearity of kinetic inductance in superconducting hybrid strip
D. Yu. Vodolazov, Yu. P. Korneeva, M. A. Dryazgov +6
We demonstrate giant nonlinearity of the kinetic inductance in a superconducting NbN/Al hybrid strip. In contrast to ordinary superconductors, where the maximum observed curr…

Native CCZ Gate with Fluxonium Qubits and a Microwave-Driven Coupler
Grigoriy S. Mazhorin, Tatyana A. Chudakova, Alena S. Kazmina +12
Native multi-qubit gates could reduce the overhead associated with decompositions into single- and two-qubit operations, but whether they can simultaneously provide high fidelity,…

4-Pixel NbN Hot-Electron Bolometer Integrated in a SiN Planar Optical Waveguide with On-Chip Fiber-Alignment Trench
N. A. Vovk, G. A. Matveev, M. A. Mumlyakov +7
In this work, we design and characterize a 4-pixel superconducting hot-electron bolometer (HEB) based on niobium nitride (NbN), integrated with individual planar silicon nitride (S…
