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…
Compatibility of quantum instruments
Chloe Kim, Yujie Zhang, Eric Chitambar +2
Measurement compatibility asks whether a family of quantum measurements can be simulated by one parent measurement followed by classical post-processing. We extend this measurement…
Randomness of exact unitary designs under symmetry
Christopher Vairogs, Felix Leditzky
We define the unitary design strength of a finite unitary ensemble to be the maximal integer for which its -th statistical moment is identical to that of the unitary group.…
A mixing time method for estimating the sample complexity of quantum state discrimination
Juntai Zhou, Felix Leditzky
We develop a mixing time method for estimating the sample complexity of quantum state discrimination. We start with considering the minimum-error discrimination of geometrically un…
A depolarizing choir sings in Gaussian harmony
Rabsan Galib Ahmed, Sujeet Bhalerao, Sungjai Lee +4
We study the noise threshold for positive quantum capacity for the qubit depolarizing channel. We explore analytically the action of the qubit depolarizing channel on the symmetric…
