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…
Entanglement Detection for Two-Qubit and Three-Qubit Pure States via Unitary Transformations and Ancilla State Measurements
Yu-Hang Liu, Yuan-Hong Tao, Yi-Wen Liu +2
The paper presents quantum circuit designs that use unitary operations and ancilla qubits to directly measure two-qubit concurrence and three-qubit 3‑tangle, avoiding full state to…
Detecting high-dimensional entanglement by randomized product projections
Jin-Min Liang, Shuheng Liu, Shao-Ming Fei +1
The characterization of high-dimensional entanglement plays a crucial role in the field of quantum information science. Conventional entanglement criteria measuring coherent superp…
Coherence Fraction in Grover Search Algorithm
Si-Qi Zhou, Hai Jin, Jin-Min Liang +3
The question of which resources drive the advantages in quantum algorithms has long been a fundamental challenge. While entanglement and coherence are critical to many quantum algo…
Wave-Particle-Mixedness Relationships Based on lp-norm Coherence
Wei-Ning Li, Ming Fang, Yuan-Hong Tao +2
We investigate the relationships among the wave property, particle property and mixedness of quantum states based on the lp-norm coherence. By conforming that the lp-norm coherence…
