Near-Optimal Mixedness Testing with Pauli Measurements

Jayadev Acharya, Abhilash Dharmavarapu, Yuhan Liu +1

We consider a fundamental problem of \emph{mixedness testing}: Given $n$ copies of an $N$ -qubit state $ρ$ , determine whether $ρ = I_{d} / d$ or $\|ρ-\mathbb{I}_d/d\|_1 \geq \va…

Establishing Mixed-State Phase Equivalence beyond Renormalization Fixed Points

Yuhan Liu

Understanding mixed-state quantum phases is a central challenge in the era of quantum simulation, where many existing studies focus on renormalization fixed points. In this work, w…
