Realizing Braided Fusion 2-Categories as (3+1)D Mixed-State Topological Orders
Ryohei Kobayashi, Abhinav Prem, Matthew Yu
We construct large families of mixed-state topological orders in (3+1)D, including intrinsically mixed-state topological orders. We realize these theories by relating the data para…
Topology from Decoherence
Alexandre Chaduteau, Derek Lee, Frank Schindler +1
Decoherence is conventionally regarded as an obstacle to realizing topological quantum phases. This has motivated extensive efforts to suppress noise in candidate topological mater…
Geometric Decoherence Time in Lindbladian Dynamics
Rishabh Jha, Stephan Haas, Abhinav Prem
The onset of decoherence in open many-body systems lacks a dynamical timescale grounded in the loss of bipartite entanglement. Here, we introduce the $tim…
Non-Equilibrium Phase Transition in a Boundary-Driven Dissipative Fermionic Chain
Hao Chen, Wucheng Zhang, Manas Kulkarni +1
We demonstrate that a boundary-localized periodic (Floquet) drive can induce nontrivial long-range correlations in a non-interacting fermionic chain which is additionally subject t…
Local-to-Global Entanglement Dynamics by Periodically Driving Impurities
Zhi-Xing Lin, Abhinav Prem, Shinsei Ryu +1
We study the entanglement dynamics of one-dimensional fermionic chains subject to a local Floquet drive of a two-site impurity, and uncover a sharp transition in the entanglement d…
Temporal Entanglement Transitions in the Periodically Driven Ising Chain
Karun Gadge, Abhinav Prem, Rishabh Jha
Periodically driven quantum systems can host non-equilibrium phenomena without static analogs, including in their entanglement dynamics. Here, we discover …
Higher-Form Anomalies Imply Intrinsic Long-Range Entanglement
Po-Shen Hsin, Ryohei Kobayashi, Abhinav Prem
We show that generic gapped quantum many-body states which respect an anomalous finite higher-form symmetry have an exponentially small overlap with any short-range entangled (SRE)…
Stabilizing Non-Abelian Topological Order against Heralded Noise via Local Lindbladian Dynamics
Sanket Chirame, Abhinav Prem, Sarang Gopalakrishnan +1
An important open question for the current generation of highly controllable quantum devices is understanding which phases can be realized as stable steady-states under local quant…
Stable Symmetry-Protected Topological Phases in Systems with Heralded Noise
Sanket Chirame, Fiona J. Burnell, Sarang Gopalakrishnan +1
We present a family of local quantum channels whose steady-states exhibit stable mixed-state symmetry-protected topological (SPT) order. Motivated by recent experimental progress o…
Periodically Driven Open Quantum Systems: Spectral Properties and Non-Equilibrium Steady States
Hao Chen, Yu-Min Hu, Wucheng Zhang +5
In this article, we investigate periodically driven open quantum systems within the framework of Floquet-Lindblad master equations. Specifically, we discuss Lindblad master equatio…
Entanglement Spectra of Stabilizer Codes: A Window into Gapped Quantum Phases of Matter
Albert T. Schmitz, Sheng-Jie Huang, Abhinav Prem
The entanglement spectrum (ES) provides a barometer of quantum entanglement and encodes physical information beyond that contained in the entanglement entropy. In this paper, we ex…
