The essence of microphysical entities
  In spite of its outstanding success, quantum mechanics remains mysterious, many problems such as wave/particle dualism and quantum nonlocality remain open. Because a particle, e.g. a photon, is a quantum of a corresponding quantum field, an arbitrary particle state directly corresponds to a quantum field, which shows the quantum field is nonlocal. A microphysical entity (ME) can be taken as the corresponding quantum field which is in the state of a quantum, where the quantum field is responsible for the ME's wave-like nature and the quantum for the ME's particle-like nature. A quantum state directly corresponds to a quantum field. Base on this simple model, many big problems in quantum physics, such as the wave/particle dualism, the collapse of the quantum state on measurement, the nonlocality in quantum entanglement, quantum teleportation, quantum swapping, and the paradox in the delayed-choice entanglement swapping, can be solved in very simple and natural manners.
