Negative quasiprobability trajectories for Bell-diagonal states under local decoherence
Qing Yu, Kun Zhang, Yang-Yang Chen +1
The fluctuation theorem (FT) relates microscopic trajectory distributions to macroscopic averages. Using quasiprobability trajectories, this framework has recently been extended to…
Diverse Dictionary Learning
Yujia Zheng, Zijian Li, Shunxing Fan +2
Given only observational data , where both the latent variables and the generating process are unknown, recovering is ill-posed without additional assumptions…
Asymptotic optimality of Grover-Radhakrishnan-Korepin algorithm
Kun Zhang, Kang-Yuan Chen, Xiao-Hui Wang +1
Grover's algorithm is a cornerstone of quantum algorithms and is strictly optimal in oracle-query complexity. While the full search problem admits no further improvement, one may t…
Asymptotic bounds on quantum partial search algorithm and its applications to parallel search
Yan-Bo Jiang, Xiao-Hui Wang, Kun Zhang +1
Grover's algorithm provides a quadratic speedup over classical algorithms for searching an unstructured database and is known to be strictly optimal in oracle query complexity, wit…
Minimal nonintegrable models with three-site interactions
Wen-Ming Fan, Kun Hao, Yang-Yang Chen +3
We study integrability breaking in translationally invariant spin- chains with genuine three-site interactions. Using a two-qubit composite representation, we prove that the d…
