Metastable confinement in Rydberg lattice gauge theories
Yaohua Li, Devendra Singh Bhakuni, Yong-Chun Liu +1
Confinement and string breaking are two fundamental phenomena in gauge theories. Signatures of both are currently pursued in quantum-simulator experiments, opening a new angle on s…
Generating large-scale Greenberger-Horne-Zeilinger-like states in lattice spin systems
Xuanchen Zhang, Yaofeng Chen, Yong-Chun Liu
Greenberger-Horne-Zeilinger (GHZ) state is a typical maximally entangled state which is pursued in both fundamental research and emerging quantum technologies. Preparing large-scal…
A Solvable Semi-infinite Fock-state-lattice SSH Model: the Stable Topological Zero Mode and the Non-Hermitian Bound Effect
Xing Yao Mi, Yong-Chun Liu, Zhi Jiao Deng +2
Fock-state lattice (FSL) offers a powerful quantum simulator for topological phenomena due to the unbounded scalability and ease of implementation. Nevertheless, the unique topolog…
Exact steady state of quantum van der Pol oscillator: critical phenomena and enhanced metrology
Yaohua Li, Xuanchen Zhang, Yong-Chun Liu
Quantum criticality of open many-body systems has attracted lots of interest for emergent phenomena and universality. Here we present the exact steady state of the quantum van der…
Fast Generation of GHZ-like States Using Collective-Spin XYZ Model
Xuanchen Zhang, Zhiyao Hu, Yong-Chun Liu
The Greenberger-Horne-Zeilinger (GHZ) state is a key resource for quantum information processing and quantum metrology. The atomic GHZ state can be generated by one-axis twisting (…
