Quantum transfer through a continuum under continuous monitoring
Luting Xu, Xin-Qi Li
In this work we extend our previous studies on the quantum transfer of a particle through a finite-bandwidth continuum under frequent detections, by replacing the assumed frequent…
Theory for frequent measurements of spontaneous emissions in non-Markovian environment: beyond Lorentzian spectrum
Luting Xu, Xin-Qi Li
The measurement-result-conditioned evolution of a system (e.g. an atom) with spontaneous emissions of photons is well described by the quantum trajectory (QT) theory. In this work…
Counting statistics of photon emissions detected in non-Markovian environment
Luting Xu, Xin-Qi Li
In this work we present a large-deviation analysis for the counting statistics of atomic spontaneous emissions continuously detected in finite-bandwidth non-Markovian environment.…
Quantum trajectories under frequent measurements in non-Markovian environment
Luting Xu, Xin-Qi Li
In this work we generalize the quantum trajectory (QT) theory from Markovian to non-Markovian environments. We model the non-Markovian environment by using a Lorentzian spectral de…
Generation and stabilization of a three-qubit entangled W state in circuit QED via quantum feedback control
Shang-Yu Huang, Hsi-Sheng Goan, Xin-Qi Li +1
Circuit cavity quantum electrodynamics (QED) is proving to be a powerful platform to implement quantum feedback control schemes due to the ability to control superconducting qubits…
Generating and stabilizing the GHZ state in circuit QED: Joint measurement, Zeno effect and feedback
Wei Feng, Peiyue Wang, Xinmei Ding +2
In solid-state circuit QED system, we extend the previous study of generating and stabilizing two-qubit Bell state [Phys. Rev. A 82, 032335 (2010)], to three-qubit GHZ state. In di…
Deterministic creation and stabilization of entanglement in circuit QED by homodyne-mediated feedback control
Zhuo Liu, Lulin Kuang, Kai Hu +4
In the solid-state circuit QED system and based on the homodyne measurement in dispersive regime, we demonstrate that a homodyne-current-based feedback can create and stabilize hig…
