Nearly Time-Optimal Pure State Tomography with Pauli Measurements
Sabee Grewal, Meghal Gupta, William He +2
We give an algorithm for pure state tomography with near-optimal copy and time complexity using only single-qubit measurements. Specifically, given copies o…

Few Single-Qubit Measurements Suffice to Certify Any Quantum State
Meghal Gupta, William He, Ryan O'Donnell
A fundamental task in quantum information science is state certification: testing whether a lab-prepared -qubit state is close to a given hypothesis state. In this work, we show…
