Microwave Photon Counter Based on Josephson Junctions
University of Wisconsin, Madison University of Waterloo
2010/11/24
The strong interaction of superconducting in-tegrated circuits with microwave photons forms
the basis of circuit quantum electrodynamics (cQED), an attractive paradigm for scalable
quantum computing...
We propose a new scheme for observing Josephson oscillations and macroscopic quantum elftrapping phenomena in a toroidally confined Bose-Einstein condensate: a dipolar self-induced

2010/11/24
We have carried out systematic Macroscopic Quantum Tunneling (MQT) experiments on Nb/Al-
AlOx/Nb Josephson junctions (JJs) of different areas. Employing on-chip lumped element inductors,we have decou...
Thermally induced 0-pi phase transition in Josephson junctions through a ferromagnetic oxide film
Thermally induced 0-pi phase transition Josephson junctions through ferromagnetic oxide film
2010/11/9
We investigate the Josephson transport through a ferromagnetic oxide film, e.g., La$_2$BaCuO$_5$, theoretically. Using the recursive Green's function technique, we found the formation of a pi-junction...

Macroscopic quantum superconducting Josephson Escape rate enhancement Josephson-Leggett mode
2010/11/5
We theoretically study the macroscopic quantum tunneling (MQT) in a hetero Josephson junction formed by a conventional single-gap superconductor and a multi-gap one such as ${MgB}_{2}$ and iron-based...

Dispersive readout scheme Josephson phase qubit
2010/11/9
We present experimental results on a dispersive scheme for reading out a Josephson phase qubit. A capacitively shunted dc-SQUID is used as a nonlinear resonator which is inductively coupled to the qub...
Theory of quantum transport in Josephson junctions with a ferromagnetic insulator
Theory of quantum Josephson junctions ferromagnetic insulator
2010/10/27
We investigate the Josephson transport through ferromagnetic insulators (FIs) by taking into
account the band structure of FIs explicitly. Using the recursive Green’s function method, we found the fo...
Photonic Josephson effect, phase transitions, and chaos in optomechanical systems
Photonic Josephson effect phase transitions chaos optomechanical systems
2010/10/20
Manifestations of quantum aspects on a macroscopic scale are supposed to bring new light on
our understanding of fundamental physics. In this paper we consider such issues among others by
analyzing ...

2010/4/6
We analyze a new long wave model describing the electrodynamics of an array of point Josephson junctions in a superconducting cavity. It consists in a wave equation with Dirac delta function sine nonl...

2010/4/13
We investigate classical thermal activation (TA) and macroscopic quantum tunneling (MQT) for a YBa$_2$Cu$_3$O$_{7-\delta}$ (YBCO) Josephson junction coupled to an LC circuit theoretically. Due to the ...

2010/4/7
We establish theoretical bounds on qubit detuning for high fidelity controlled-NOT logic gate implementations with weakly coupled Josephson phase qubits. It is found that the value of qubit detuning d...
