Sublinear Copies Suffice for Fidelity Estimation with Pauli Measurements

Jayadev Acharya, Abhilash Dharmavarapu, Yuhan Liu +1

We present a protocol that estimates the quantum fidelity, up to precision $ε$ , between a known target state and unknown lab-prepared state with sublinear, $o(d^{0.9908}/…

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…
