Rademacher complexity of noisy quantum circuits
Kaifeng Bu, Dax Enshan Koh, Lu Li +2
Noise in quantum systems is a major obstacle to implementing many quantum algorithms on large quantum circuits. In this work, we study the effects of noise on the Rademacher comple…
Benchmarking one-shot distillation in general quantum resource theories
Bartosz Regula, Kaifeng Bu, Ryuji Takagi +1
We study the one-shot distillation of general quantum resources, providing a unified quantitative description of the maximal fidelity achievable in this task, and revealing similar…
One-Shot Operational Quantum Resource Theory
Zi-Wen Liu, Kaifeng Bu, Ryuji Takagi
A fundamental approach for the characterization and quantification of all kinds of resources is to study the conversion between different resource objects under certain constraints…
Efficient classical simulation of Clifford circuits with nonstabilizer input states
Kaifeng Bu, Dax Enshan Koh
We investigate the problem of evaluating the output probabilities of Clifford circuits with nonstabilizer product input states. First, we consider the case when the input state is…
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…
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…
