Quantifying the resource content of quantum channels: An operational approach
Lu Li, Kaifeng Bu, Zi-Wen Liu
We propose a general method to operationally quantify the resourcefulness of quantum channels via channel discrimination, an important information processing task. A main result is…

Classical simulation of quantum circuits by half Gauss sums
Kaifeng Bu, Dax Enshan Koh
We give an efficient algorithm to evaluate a certain class of exponential sums, namely the periodic, quadratic, multivariate half Gauss sums. We show that these exponential sums be…

Operational Advantage of Quantum Resources in Subchannel Discrimination
Ryuji Takagi, Bartosz Regula, Kaifeng Bu +2
One of the central problems in the study of quantum resource theories is to provide a given resource with an operational meaning, characterizing physical tasks in which the resourc…
