Open AccessJosephson radiation threshold detector
A Josephson radiation threshold detector (JRTD) that is based on the threshold behaviour of a current bias Josephson junction (CBJJ) is designed and fabricated for infrared radiation (IR@1550nm) detection at l...

A Superconducting RF Low-Pass Filter Based on Ti/TiN Artificial Transmission Line for Detector and Qubit Readout
Cryogenic detector and qubit readout systems often include radio-frequency low-pass filters (LPFs) at the input/output paths to protect the sensitive devices from stray radiation traveling down the coaxial lin...

Open AccessA microwave scattering spectral method to detect the nanomechanical vibrations embedded in a superconducting qubit
Nanomechanical resonators (NMRs), as the quantum mechanical sensing probers, have played the important roles for various high-precision quantum measurements. Differing from the previous emission spectral probe...

Electric current induced by microwave Stark effect of electrons on liquid helium
We propose a frequency-mixed effect of terahertz (THz) and gigahertz (GHz) electromagnetic waves in the cryogenic system of electrons floating on liquid helium surface. The THz wave is near-resonant with the t...

Measurement of Optical Constants of TiN and TiN/Ti/TiN Multilayer Films for Microwave Kinetic Inductance Photon-Number-Resolving Detectors
We deposit thin titanium nitride (TiN) and TiN/Ti/TiN multilayer films on sapphire substrates and measure the reflectance and transmittance in the wavelength range from 400 to 2000 nm using a spectrophotometer...

Open AccessQuantifying quantum coherence with quantum Fisher information
Quantum coherence is one of the old but always important concepts in quantum mechanics, and now it has been regarded as a necessary resource for quantum information processing and quantum metrology. However, t...

Dynamics of Spinor Condensates Driven by an Inhomogeneous Magnetic Field
A variational wavefunction including the breather, dipole and scissor modes simultaneously is constructed to investigate the collective-excitation dynamics of spin-1

Hawking radiation temperatures in non-stationary Kerr black holes with different tortoise coordinate transformations
We apply the Damour–Ruffini–Sannan method to study the Hawking radiations of scalar and Dirac particles in non-stationary Kerr black holes under different tortoise coordinate transformations. We found that all...

Modelling of Multi-Ion-Beam Reactive Cosputtering for Metal Oxide Thin Films
Very recently a new technique named multi-ion-bram reactive cosputtering(MIBRECS) was developed for preparing multi-component metal oxide thin films. Epitaxial or highly oriented (Pb,La) TiO3 thin films sputtered...
