Two Mode Photon Bunching Effect as Witness of Quantum Criticality in Circuit QED
Qing Ai, Ying-Dan Wang, Guilu Long +1
We suggest a scheme to probe critical phenomena at a quantum phase transition (QPT) using the quantum correlation of two photonic modes simultaneously coupled to a critical system.…
Cooling a micro-mechanical resonator by quantum back-action from a noisy qubit
Ying-Dan Wang, Yong Li, Fei Xue +2
We study the role of qubit dephasing in cooling a mechanical resonator by quantum back-action. With a superconducting flux qubit as a specific example, we show that ground-state co…
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…
