Coupling superconducting flux qubits at optimal point via dynamic decoupling with the quantum bus
Y. D. Wang, A. Kemp, K. Semba
We propose a scheme with dc-control of finite bandwidth to implement two-qubit gate for superconducting flux qubits at the optimal point. We provide a detailed non-perturbative ana…
Quantum Theory of Transmission Line Resonator-Assisted Cooling of a Micromechanical Resonator
Yong Li, Ying-Dan Wang, Fei Xue +1
We propose a quantum description of the cooling of a micromechanical flexural oscillator by a one-dimensional transmission line resonator via a force that resembles cavity radiatio…
Cooling of a Micro-mechanical Resonator by the Back-action of Lorentz Force
Y. D. Wang, K. Semba, H. Yamaguchi
Using a semi-classical approach, we describe an on-chip cooling protocol for a micro-mechanical resonator by employing a superconducting flux qubit. A Lorentz force, generated by t…
Controllable Coupling between Flux Qubit and Nanomechanical Resonator by Magnetic Field
Fei Xue, Y. D Wang, C. P. Sun +3
We propose an active mechanism for coupling the quantized mode of a nanomechanical resonator to the persistent current in the loop of a superconducting Josephson junction (or phase…
Quantum Heat Engines Using Superconducting Quantum Circuits
H. T. Quan, Y. D. Wang, Yu-xi Liu +2
We propose a quantum analog of the internal combustion engine used in most cars. Specifically, we study how to implement the Otto-type quantum heat engine (QHE) with the assistance…
Fast entanglement of two charge-phase qubits through nonadiabatic coupling to a large junction
Y. D. Wang, P. Zhang, D. L. Zhou +1
We propose a theoretical protocol for quantum logic gates between two Josephson junction charge-phase qubits through the control of their coupling to a large junction. In the low e…
