Lieb-Schultz-Mattis Constraints for Quantum Channels: A Spacetime-Duality View
Sarang Gopalakrishnan, Yu-Jie Liu, Tsung-Cheng Lu +2
Quantum anomalies strongly constrain the possible behavior of many-body systems. A prime example is the Lieb-Schultz-Mattis (LSM) theorem, which relates UV symmetry and filling con…
Digital dissipative state preparation for frustration-free gapless quantum systems
Johannes Feldmeier, Yu-Jie Liu, Mikhail D. Lukin +1
Preparing algebraically correlated ground states of quantum many-body systems is an important, yet challenging task for quantum simulation. We introduce a protocol that employs loc…
Holographic duality between bulk topological order and boundary mixed-state order
Tsung-Cheng Lu, Yu-Jie Liu, Sarang Gopalakrishnan +1
We introduce a holographic framework for analyzing the steady states of repeated quantum channels with strong symmetries. Using channel-state duality, we show that the steady state…
Skeleton of isometric Tensor Network States for Abelian String-Net Models
Julian Boesl, Yu-Jie Liu, Frank Pollmann +1
We construct parametrized isometric tensor network states -- referred to as skeletons -- that allow us to explore phases of abelian topological order and can be efficiently impleme…
Information-theoretic principle of emergent 1-form symmetries
Yu-Jie Liu, Wen-Tao Xu, Frank Pollmann +1
Higher-form symmetries act on sub-dimensional spatial manifolds of a quantum system. They can emerge as an exact symmetry at low energies even when they are explicitly broken at th…
Simulating 2D topological quantum phase transitions on a digital quantum computer
Yu-Jie Liu, Kirill Shtengel, Frank Pollmann
Efficient preparation of many-body ground states is key to harnessing the power of quantum computers in studying quantum many-body systems. In this work, we propose a simple method…
