Decoherence-free interaction and maximally entangled state generation in giant-atom semi-infinite waveguide systems
Jie Liu, Yue Cai, Lei Tan
Giant atoms are artificial atoms that can couple to a waveguide non-locally. Previous works have shown that two giant atoms in a braided configuration can interact through one-dime…
Quantum phase transition in two dimension nonlinear cavity optomagnonic system
Yu Sang, Jie Liu, Lei Tan
The superfluid-Mott insulator and ergodic-many body localization transitions based on a two dimension nonlinear cavity optomagnonic system are investigated, where a yttrium iron ga…
Multifunctional Nonreciprocal Quantum Device Based on Superconducting Quantum Circuit
Yue Cai, Jie Liu, Kang-Jie Ma +1
Nonreciprocal devices, such as isolator or circulator, are crucial for information routing and processing in quantum networks. Traditional nonreciprocal devices, which rely on the…
Entanglement transfer between giant atoms in waveguide-QED systems
Jie Liu, Zhi-Qiang Liu, Yu Sang +1
We investigate the entanglement transfer between giant atoms in waveguide-QED systems. The system consists of two pairs of two-level giant atoms, and , each independently…
Highly Scalable Quantum Router with Frequency-Independent Scattering Spectra
Yue Cai, Kang-Jie Ma, Jie Liu +3
Optical quantum routers play a crucial role in quantum networks and have been extensively studied in both theory and experiment, leading to significant advancements in their perfor…
Entanglement enhancement of two giant atoms with multiple connection points in bidirectional-chiral quantum waveguide-QED system
Jie Liu, Yue Cai, Kang-Jie Ma +2
We study the entanglement generation of two giant atoms within a one-dimensional bidirectional-chiral waveguide quantum electrodynamics (QED) system, where the initial state of the…
