Abstract: London presented a relation between suppercurrent density and magnetic vector potential [1], Pippard suggested a non-local relation [2], and the similar relation can be derived with the BCS ...
Numerical method to optimize the Polar-Azimuthal Orientation of Infrared Superconducting Nanowire Single-Photon Detectors
Numerical method Infrared Superconducting Nanowire
2011/9/2
A novel finite-element method for calculating the illumination-dependence of absorption in three-dimensional nanostructures is presented based on the RF module of the COMSOL software package. This met...
Landau-Zener-Stückelberg Spectroscopy of a Superconducting Flux Qubit
Landau-Zener-Stückelberg Spectroscopy Superconducting Flux Qubit
2010/10/20
We proposed a new method to measure the energy spectrum of a superconducting flux qubit.
Different from the conventional frequency spectroscopy, a short triangle pulse is used to drive the qubit thro...

2010/10/27
We propose an architecture based on superconducting qubits and resonators for the implementation of a variety of exotic lattice systems, such as spin and Hubbard models in higher or fractal dimensions...
Temperature Dependent Performances of Superconducting Nanowire Single-Photon Detectors in an Ultralow-Temperature Region
Temperature Dependent Performances Superconducting Nanowire Single-Photon Detectors Ultralow-Temperature Region
2010/10/20
We present the performances of a superconducting nanowire single-photon detector (SNSPD) in an ultralow-temperature region from 16 mK to 4 K. The system detection efficiency of the SNSPD showed satura...
Compactly packaged superconducting nanowire single-photon detector with an optical cavity for multichannel system
superconducting single-photon
2010/3/10
We developed superconducting nanowire single-photon detectors with an optical cavity (OC-SNSPDs) for multichannel systems. For efficient coupling, the devices were installed in compact fiber-coupled p...
