What the wave function really describes may be random discontinuous motion of particles
We consider the meaning of the wave function from a new angle. It is suggested that the wave function in quantum mechanics, like the trajectory function in classical mechanics that describes the deterministic continuous motion of particles, also describes the motion of particles, which is random and discontinuous in nature. The random discontinuous motion of particles is then taken as the quantum reality hiding behind the wave function. We argue that this strange picture of quantum reality is implied not only by the protective measurement in quantum mechanics, but also by the familiar phenomenon of inertial motion in the macroscopic world. Further mathematical analysis supports the new interpretation of the wave function.

Distillability of entanglement in noninertial frames
There has recently been some interest in effects of both special and general relativity on quantum entanglement .  Investigations show that a state which is maximally entangled in an inertial frame becomes less entangled if the observers are relatively accelerated. The presence of a horizon for uniformly accelerated observers results in a loss of information and a corresponding degradation of entanglement. This phenomenon, which is a consequence of the Unruh effect, shows that entanglement is an observer-dependent quantity in noninertial frames. In this research work, to illustrate the effects of acceleration on distillability and separability, we provide an analysis of quantum entanglement of dirac field in non-inertial  reference frames in the context of Werner states. This analysis help us to understand the relationship between relativity and quantum information theory. The study of Werner states allowed us to show that distillability is a relative concept, depending on the frame in which it is observed. We show that there are states that will change from distillable (entangled) state into separable for a certain value of acceleration, showing the effects of acceleration on distillability and separability.
