Native CCZ Gate with Fluxonium Qubits and a Microwave-Driven Coupler
Grigoriy S. Mazhorin, Tatyana A. Chudakova, Alena S. Kazmina +12
The paper reports an experimental demonstration of a native three-qubit controlled-controlled-phase (CCZ) gate using fluxonium qubits coupled via a microwave-driven transmon couple…
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…
Control of thin NbN film superconducting properties by ScN buffer layer
N. V. Porokhov, M. A. Dryazgov, A. R. Shevchenko +7
This work investigates the effect of a scandium nitride buffer layer on the superconducting properties of niobium nitride thin films. The use of a ScN buffer layer significantly im…
Practical way to increase nonlinearity of kinetic inductance of superconductor
Yu. P. Korneeva, M. A. Dryazgov, I. V. Trofimov +7
This work demonstrates that depositing a thin layer of Mo (5-15 nm) onto a 10 nm thick NbN strip leads to a significant increase in the nonlinearity of the kinetic inductance …
Response of a Cold-Electron Bolometer in a coplanar antenna system
D. A. Pimanov, A. L. Pankratov, A. V. Gordeeva +13
Cold electron bolometers have shown their suitability for use in modern fundamental physical experiments. Fabrication and measurements of the samples with cold-electron bolometers…
