Design of deeply cooled ultra-low dissipation amplifier and measuring cell for quantum measurements with a microwave single-photon counter
O. G. Turutanov, A. M. Korolev, V. I. Shnyrkov +6
The requirements and details of designing a measuring cell and low-back-action deeply-cooled amplifier for quantum measurements at 10 mK are discussed. This equipment is a part of…
Integrated conversion and photodetection of virtual photons in an ultrastrongly coupled superconducting quantum circuit
Luigi Giannelli, Giorgio Anfuso, Miroslav Grajcar +3
The ground-state of an artificial atom ultrastrongly coupled to quantized modes is entangled and contains an arbitrary number of virtual photons. The problem of their detection has…
Detecting virtual photons in ultrastrongly coupled superconducting quantum circuits
Luigi Giannelli, Elisabetta Paladino, Miroslav Grajcar +2
Light-matter interaction and understanding the fundamental physics behind is essential for emerging quantum technologies. Solid-state devices may explore new regimes where coupling…
Superconducting source and sensor of single bubbles to study nucleate boiling of liquid helium
A. G. Sivakov, O. G. Turutanov, S. A. Kruhlov +5
Joule heat generated by resistive elements of cryogenic micro- and nanodevices often originates boiling of the cooling cryogenic liquids (helium, nitrogen). The article proposes an…
Reflection-enhanced gain in traveling-wave parametric amplifiers
S. Kern, P. Neilinger, E. Iľichev +12
The operating principle of traveling-wave parametric amplifiers is typically understood in terms of the standard coupled mode theory, which describes the evolution of forward propa…
Zeeman driven superconductor insulator transition in strongly disordered MoC film. STM and transport studies in transverse magnetic field
M. Žemlička, M. Kopčík, P. Szabó +5
Superconductor insulator transition in transverse magnetic field is studied in the highly disordered MoC film with the product of the Fermi momentum and the mean free path …
