Fisher discord as a quantifier of quantum complexity
Huihui Li, Shunlong Luo, Yue Zhang
Two classically equivalent expressions of mutual information of probability distributions (classical bipartite states) diverge when extended to quantum systems, and this difference…

Quantifying complexity of continuous-variable quantum states via Wehrl entropy and Fisher information
Siting Tang, Francesco Albarelli, Yue Zhang +2
The notion of complexity of quantum states is quite different from uncertainty or information contents, and involves the tradeoff between its classical and quantum features. In thi…

An Efficient Quantum Classifier Based on Hamiltonian Representations
Federico Tiblias, Anna Schroeder, Yue Zhang +2
Quantum machine learning (QML) is a discipline that seeks to transfer the advantages of quantum computing to data-driven tasks. However, many studies rely on toy datasets or heavy…
