On Optimal Quantum Data Hiding and Maximal Separable Ball
Zhi Li
Quantum data hiding asks how much distinguishing power can be lost when global measurements are restricted to local measurements and classical communication. In this work, we estab…
Many-body chirality of topological stabilizer states
Tyler D. Ellison, Dongjin Lee, Zhi Li +3
A defining feature of chirality is the distinction between a system and its mirror image. Despite extensive experimental observations of chiral phases and theoretical advances, a q…
Tripartite Haar random state has no bipartite entanglement
Zhi Li, Takato Mori, Beni Yoshida
We show that no EPR-like bipartite entanglement can be distilled from a tripartite Haar random state by local unitaries or local operations when each subsystem $…
A Unified Framework for Locally Stable Phases
Zhi Li, Raz Firanko, Timothy H. Hsieh
We propose a unifying framework for characterizing pure and mixed state phases of matter across equilibrium, non equilibrium, and metastable regimes. We introduce the concept of lo…
Explicit States with Two-sided Long-Range Magic
Zhi Li
Nonstabilizerness, or magic, is a necessary resource for quantum advantage beyond the classically simulatable Clifford framework. Recent works have begun to chart the structure of…
Entanglement sharing schemes
Zahra Khanian, Dongjin Lee, Debbie Leung +7
We ask how quantum correlations can be distributed among many subsystems. To address this, we define entanglement sharing schemes (ESS) where certain pairs of subsystems allow enta…
