Microwave Photon Counter Based on Josephson Junctions
Y. -F. Chen, D. Hover, S. Sendelbach +5
We describe a microwave photon counter based on the current-biased Josephson junction. The junction is tuned to absorb single microwave photons from the incident field, after which…
Decoherence by electromagnetic fluctuations in double-quantum-dot charge qubits
Diego C. B. Valente, Eduardo R. Mucciolo, F. K. Wilhelm
We discuss decoherence due to electromagnetic fluctuations in charge qubits formed by two lateral quantum dots. We use an effective circuit model to evaluate correlations of voltag…
The size of macroscopic superposition states in flux qubits
J. I. Korsbakken, F. K. Wilhelm, K. B. Whaley
The question as to whether or not quantum mechanics is applicable to the macroscopic scale has motivated efforts to generate superposition states of macroscopic numbers of particle…
Stationary and transient leakage current in the Pauli spin blockade
F. Qassemi, W. A. Coish, F. K. Wilhelm
We study the effects of cotunneling and a non-uniform Zeeman splitting on the stationary and transient leakage current through a double quantum dot in the Pauli spin blockade regim…
Quantum trajectory equation for multiple qubits in circuit QED: Generating entanglement by measurement
Chantal L. Hutchison, J. M. Gambetta, Alexandre Blais +1
In this paper we derive an effective master equation and quantum trajectory equation for multiple qubits in a single resonator and in the large resonator decay limit. We show that…
Crossover from weak to strong coupling regime in dispersive circuit QED
I. Serban, E. Solano, F. K. Wilhelm
We study the decoherence of a superconducting qubit due to the dispersive coupling to a damped harmonic oscillator. We go beyond the weak qubit-oscillator coupling, which we associ…
