Symmetric joint measurement as a complement to the elegant joint measurement

Ying-Qiu He, Yu-Yan Zhang, Dong Ding +2

Traditional Bell state measurement (BSM) and product basis measurements (PBM) have been integral to nearly the entire development of quantum computing. Unlike the BSM and the PBM,…

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…

-type quantum network configuration and its nonlocality

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…

Quantum teleportation based on the elegant joint measurement

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…

A scalable tripartite Wigner's friend scenario

Dong Ding, Can Wang, Ying-Qiu He +3

Wigner's friend thought experiment is intended to reveal the inherent tension between unitary evolution and measurement collapse. On the basis of Wigner's friend experiment, Brukne…

On six-photon entangled state emitted from a single third-order parametric down-conversion process

Ying-Qiu He, Dong Ding, Ting Gao +1

We consider six-photon entangled state emitted from a single third-order parametric down-conversion process. In the regime of weak nonlinearities, we present a symmetry detector wh…

Violation of generalized Bell inequality and its optimal measurement settings

Dong Ding, Yingqiu He, Fengli Yan +1

We provide a method to describe quantum nonlocality for -qubit systems. By treating the correlation function as an -index tensor, we derive a generalized Bell inequality. Tak…
