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…

Sampling and Identity-Testing Without Approximate Tensorization of Entropy
William Gay, William He, Nicholas Kocurek +1
Certain tasks in high-dimensional statistics become easier when the underlying distribution satisfies a local-to-global property called approximate tensorization of entropy (ATE).…

Pseudorandomness Properties of Random Reversible Circuits
William Gay, William He, Nicholas Kocurek +1
Motivated by practical concerns in cryptography, we study pseudorandomness properties of permutations on computed by random circuits made from reversible -bit gates…
