Abstract

Abstract 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 wave-particle duality in tripartite systems. We perform quantum state tomography to reconstruct the reduced density matrix by using the OriginQ quantum computing cloud platform. As a result, we show that, theoretically and experimentally, the quantitative wave-particle duality is indeed constrained by the global tripartite entanglement.
The present constraint relation can not only provide the foundational explanation for experimentally testing wave-particle duality, and also give the global entanglement a motivated physical meaning from the point of view of the quantitative wave-particle duality.
