Translation-Invariant Pure States with Exotic Half-Chain Factors
Ruizhi Liu, Jinmin Yi
We construct translation-invariant pure quasifree fermionic states on the one-dimensional lattice whose half-chain von Neumann algebras are hyperfinite factors of type $\mathrm{II}…
A local description of strong symmetries and strong-to-weak symmetry breaking in quantum many-body systems
Ruizhi Liu, Jinmin Yi, Dominic V. Else
In mixed states of quantum systems, symmetries come in two types: strong and weak. Furthermore, it has been argued that in quantum many-body systems, strong symmetries can be "spon…
Lovász Meets Lieb-Schultz-Mattis: Complexity in Approximate Quantum Error Correction
Jinmin Yi, Ruizhi Liu, Zhi Li
Approximate quantum error correction (AQEC) provides a versatile framework for both quantum information processing and probing many-body entanglement. We reveal a fundamental tensi…
On whether quantum theory needs complex numbers: the foil theories perspective
Yìlè Yīng, Maria Ciudad Alañón, Daniel Centeno +5
Recent work by Renou et al. (2021) has led to some controversy concerning the question of whether quantum theory requires complex numbers for its formulation. We promote the view t…
