  As a fundamental characteristic of physical entities, waveparticle duality
describes whether a microscopic entity exhibits wave or particle attributes
depending on the specific experimental setup. This assumption is premised on
the notion that physical properties are inseparable from the objective carrier.
However, after the concept of the quantum Cheshire cats was proposed, which
makes the separation of physical attributes from the entity possible, the
premise no longer holds. Furthermore, an experimental demonstration of the
separation of the wave and particle attributes inspired by this scenario
remains scarce. In this work, we experimentally separated the wave and particle
attributes of a single photon by exploiting the quantum Cheshire cat concept
for the first time. By applying a weak disturbance to the evolution of the
system, we achieve an effect similar to the quantum Cheshire cat and
demonstrated the separation of the wave and particle attributes via the
extraction of weak values. Our work provides a new perspective for the indepth
understanding of waveparticle duality and promotes the application of weak
measurements in fundamentals of quantum mechanics.
