Quantum speed limits based on quantifiers of quantum-state texture
Yuhang Xie, Yanjun Chu, Chenyang Cui +1
Quantum speed limits impose intrinsic lower bounds on the shortest time scale for quantum system evolution. As an emerging paradigm in quantum resource theory, quantum-state textur…

Quantum-state block texture and its quantification
Yanjun Chu, Yuhang Xie, Chenyang Cui +1
Quantum-state texture (QST) is an emerging quantum resource that has garnered increasing attention amid advances in quantum theory. In this work, we generalize the QST to quantum-s…

Identifying local unitary equivalence based on reduction of quantum states
Yanjun Chu, Chenyang Cui, Yuhang Xie +2
Local unitary equivalence is central to entanglement quantification and classification. Identifying the local unitary equivalence remains a formidable challenge. We address this pr…
