Bound state in the continuum and dynamics via phase modulation in giant-atom waveguide setups
Ji Qi, Xiaojun Zhang, Honngwei Yu +1
Giant atoms, which couple to a waveguide through multiple spatially separated connection points beyond the dipole approximation, provide a versatile route for quantum information p…
Giant emitter magnetometer
Xiaojun Zhang, Xiang Guo, Zhihai Wang
Leveraging the sensitive dependence of a giant atom's radiation rate on its frequency [A. F. Kockum, ., Phys. Rev. A 90, 013837 (2014)], we propose an effective magnetometer…
Rabi oscillation and fractional population via the bound states in the continuum in a giant atom waveguide QED setup
Hongwei Yu, Xiaojun Zhang, Zhihai Wang +1
We study the dynamics of two giant atoms interacting with a coupled resonator waveguide (CRW) beyond the Markovian approximation. The distinct atomic configurations determine the n…
Phase-controlled bound states in giant atom waveguide QED setup
Xiaojun Zhang, Mingjie Zhu, Zhihai Wang
We find the phase-controlled bound state out of the continuum~(BOC) and bound state in the continuum~(BIC) in an artificial giant atom dressed one-dimensional photonic waveguide wh…
Quantum interference and controllable magic cavity QED via a giant atom in coupled resonator waveguide
Xiaojun Zhang, Chengge Liu, Zhirui Gong +1
We study the Markovian and Non-Markovian dynamics in a giant atom system which couples to a coupled resonator waveguide (CRW) via two distant sites. Under certain conditions, we fi…
Superconducting giant atom waveguide QED: Quantum Zeno and Anti-Zeno effects in ultrastrong coupling regime
Xiaojun Zhang, Weijun Cheng, Zhirui Gong +2
The giant atom system is a new paradigm in quantum optics, in which the traditional dipole approximation is not available. In this paper, we construct an artificial giant atom mode…
Preparation of cluster states and W states with superconducting- quantum-interference-device qubits in cavity QED
X. L. Zhang, K. L. Gao, M. Feng
We propose schemes to create cluster states and W states by many superconducting-quantum-interference-device (SQUID) qubits in cavities under the influence of the cavity decay. Our…
