Quantum thermal diode with additional control by auxiliary atomic states
Qin Zhang, Zi-chen Zhang, Yi-jia Yang +2
A quantum thermal diode, similar to an electronic diode, allows for unidirectional heat transmission. In this paper, we study a quantum thermal diode composed of two two-level atom…
Analysis of measurement errors for a superconducting phase qubit
Qin Zhang, Abraham G. Kofman, John M. Martinis +1
We analyze several mechanisms leading to errors in a course of measurement of a superconducting flux-biased phase qubit. Insufficiently long measurement pulse may lead to nonadiaba…
Theory of measurement crosstalk in superconducting phase qubits
A. G. Kofman, Q. Zhang, J. M. Martinis +1
We analyze the crosstalk error mechanism in measurement of two capacitively coupled superconducting flux-biased phase qubits. The damped oscillations of the superconducting phase a…
Continuous quantum feedback of coherent oscillations in a solid-state qubit
Qin Zhang, Rusko Ruskov, Alexander N. Korotkov
We have analyzed theoretically the operation of the Bayesian quantum feedback of a solid-state qubit, designed to maintain perfect coherent oscillations in the qubit for arbitraril…
