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…
Streaming quantum state purification for general mixed states
Daniel Grier, Debbie Leung, Zhi Li +2
Given multiple copies of a mixed quantum state with an unknown, nondegenerate principal eigenspace, quantum state purification is the task of recovering a quantum state that is clo…
Complete space-like self-expanders in the Minkovski space
Zhi Li, Guoxin Wei
It is our purpose to study complete space-like self-expanders in the Minkovski space. By use of maximum principle of Omori-Yau type, we can obtain the rigidity theorems on -dime…
Rogers-Ramanujan type identities involving double, triple and quadruple sums
Zhi Li, Liuquan Wang
We prove a number of new Rogers-Ramanujan type identities involving double, triple and quadruple sums. They were discovered after an extensive search using Maple. The main idea of…
