Evidence of the quantum entanglement constraint on wave-particle duality

A researchers team at EPFL, Switzerland, has experimentally verified the link existing between entanglement and the amount of wave-particle duality in a bipartite quantum system, with superconducting qubits in the IBM Q quantum computer.

They have analyzed both pure and mixed states, and studied the limitations of the state purity on the complementarity triality relation. This work confirms the quantitative completion of local Bohr’s complementarity principle by the nonlocal quantum entanglement for a bipartite quantum system. (EPFL)
