Tight Universal Bounds on Quantum Data Hiding with Multipartite Werner States
Oren Akresh, Jacob Beckey, Felix Leditzky
Quantum data hiding concerns pairs of states which are highly distinguishable with global measurements, yet nearly indistinguishable when restricted to local operations and classic…

Tight Bounds for Purity and Product Testing from Partial Transposition
Oren Akresh, Jacob Beckey
Coherent measurements across multiple copies of an unknown quantum state can substantially reduce the number of samples required to learn its properties, but remain experimentally…
