- Abstract: 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.

In our common sense, the wave and particle properties of a quantum object are inseparable.
In this study, we put forward a feasible scheme to spatially separate the wave and particle attributes of two entangled photons.
Our scheme also guarantees that the observation of wave and particle properties of the two entangled photons always obey the Bohr's complementarity principle.

Two particles are identical if all their intrinsic properties, such as spin and charge, are the same.
Quantum mechanics is seen as a normative and algorithmic theory guiding an agent to assess her subjective beliefs represented as (coherent) sets of gambles.
We show how sets of exchangeable observables (gambles) may be updated after a measurement and discuss the issue of defining entanglement for indistinguishable particle systems.

We propose an interpretative framework for quantum mechanics corresponding to the specifications of Louis de Broglie's double-solution theory.
The principle is to decompose the evolution of a quantum system into two wave functions.
For Schr"odinger, the particles are extended and the square of the module of the (internal) wave function of an electron corresponds to the density of its charge in space.
