Mixed-State Symmetry-Protected Topology and Strong-to-Weak Spontaneous Symmetry Breaking in a Superconducting Qubit Array
Qian Cao, Zhen Bi, Kater W. Murch
We experimentally investigate how symmetry-protected topological order in a one-dimensional cluster state is transformed by measurement and decoherence in a five-qubit superconduct…
Dissipative Preparation of Correlated Quantum States in Dipolar Rydberg Arrays
Mingsheng Tian, Zhen Bi, Thomas Iadecola +1
Preparing correlated quantum states is essential for emerging technologies, but remains challenging in many-body systems. Here we propose a dissipative protocol that engineers nonr…
Intertwining Josephson and Vortex Topologies in Conventional Superconductors
Zhuo Chen, Jiangxu Li, Lun-Hui Hu +2
Recent experimental advances have unveiled promising evidence of vortex-bound Majorana quasiparticles in multiple superconducting compounds. However, theoretical progress in unders…
Indirect Tunneling Enabled Spontaneous Time-Reversal Symmetry Breaking and Josephson Diode Effect in TiN/AlO/HfZrO/Nb tunnel junctions
Shaoqing Ding, Jinyuan Yao, Zhen Bi +6
Josephson diode (JD) effect found in Josephson tunnel junctions (JTJs) has attracted a great deal of attention due to its importance for developing superconducting circuitry based…
Intrinsic (Axion) Statistical Topological Insulator
Xi Chen, Fa-Jie Wang, Zhen Bi +1
Ensembles that respect symmetries on average exhibit richer topological states than those in pure states with exact symmetries, leading to the concept of average symmetry-protected…
-Nontrivial Moiré Minibands and Interaction-Driven Quantum Anomalous Hall Insulators in Topological Insulator Based Moiré Heterostructures
Kaijie Yang, Zian Xu, Yanjie Feng +6
We studied electronic band structure and topological property of a topological insulator thin film under a moiré superlattice potential to search for two-dimensional (2D) $\mathbb…
