Quantum chi-squared tomography and mutual information testing

Steven T. Flammia, Ryan O'Donnell

For quantum state tomography on rank- $r$ dimension- $d$ states, we show that $O (r^{.5} d^{1.5} / ε) \leq O (d^{2} / ε)$ copies suffice for accuracy~ $ε$ with respect…

Query-optimal estimation of unitary channels in diamond distance

Jeongwan Haah, Robin Kothari, Ryan O'Donnell +1

We consider process tomography for unitary quantum channels. Given access to an unknown unitary channel acting on a $d$ -dimensional qudit, we aim to output a classical des…
