  Wave and particle are two fundamental properties of Nature. The wave-particle
duality has indicated that a quantum object may exhibit the behaviours of both
wave and particle, depending upon the circumstances of the experiment. The
major significance of wave-particle duality has led to a fundamental equation
in quantum mechanics, the Schr{\" o}dinger equation. At present, the principle
of wave-particle duality has been deeply rooted in people's hearts. This gives
rise to a common sense perception that wave property and particle property
coexist simultaneously in a quantum entity, and these two physical attributes
cannot be completely separated from each other. In classical physics, a similar
common sense is that a physical system is inseparable from its physical
properties. However, this has been recently challenged and beaten by a quantum
phenomenon called the "quantum Cheshire cat", for which a cat and its grin can
be separated spatially. In this work, we propose a thought experiment based on
the similar technology of quantum Cheshire cat. We find that wave and particle
attributes of a quantum entity can be completely separated, thus successfully
dismantling the wave-particle duality for a quantum entity. Our result is still
consistent with the complementarity principle and deepens the understanding of
quantum foundations.
