Variational Quantum Algorithm for Constrained Combinatorial Optimization Problems
Hui-Min Li, Yuan-Liang Han, Zhi-Xi Wang +1
While variational quantum algorithms (VQAs) have demonstrated considerable success in unconstrained optimization, their application to constrained combinatorial problems face a tra…
Symmetric quantum joint measurements on multiple qubits
Dong Ding, Ying-Qiu He, Ting Gao +1
We investigate the generalization of symmetric quantum joint measurements on multiple qubits. We first describe a method for constructing a symmetric joint measurement basis for th…
A more generalized two-qubit symmetric quantum joint measurement
Ying-Qiu He, Dong Ding, Ting Gao +2
A standard two-qubit joint measurement is the well-known Bell state measurement (BSM), in which each reduced state (traced out one qubit) is the completely mixed state. Recently, a…

Zan-Jia Li, Ying-Qiu He, Dong Ding +3
A quantum network shared entangled sources among distant nodes enables us to distribute entanglement along the network by suitable measurements. Network nonlocality means that it d…

Dong Ding, Ming-Xing Yu, Ying-Qiu He +3
As a generalization of the well-known Bell state measurement (BSM), the elegant joint measurement (EJM) is a kind of novel two-qubit joint measurement, parameterized by a subtle ph…
Entanglement constraint on wave-particle duality for tripartite systems
Zanjia Li, Yingqiu He, Dong Ding +2
A global multi-partite entanglement may place a constraint on the wave-particle duality. We investigate this constraint relation of the global entanglement and the quantitative wav…
