V.; Home, Dipankar Without any classical channels, quantum information can be transferred using an entangled tripartite system with nonorthogonal states. We give a specific dynamical model for the preparation of such an entangled tripartite system. As a consequence we obtain a quantum non-local effect which is not of the Bell type.

Examples are given for two, three and four identical particles prepared in two, three or four distinct states, respectively. We show that the identical nature of the particles can be probed through entanglement and their specific statistics can be probed by discriminating between types of entangled states.

This is specifically illustrated by using the modulus of the probability current density for calculating the arrival/transit time distribution of spin-1/2 neutral particles at the exit point of a spin-rotator (SR) which contains a constant magnetic field. Such a calculated time distribution is then used for evaluating the distribution of spin orientations along different directions for these particles emerging from the SR. Based on this, the result of spin measurement along any arbitrary direction for such an ensemble is predicted.

M.; Majumdar, A.S.; Home, Dipankar The phenomenon of quantum superarrivals is manifested in the probabilities for Schrodinger wave packets scattered from perturbed potential barriers. We argue that both classical wave-like and classical particle-like properties can be exhibited in the same gedanken experimental setup for obtaining superarrivals through Schrodinger dynamics. An interesting question regarding the tenet of mutual exclusiveness, a la Bohr, of these two properties is raised in the context of this phenomenon. DOI: 10.1007/s10702-006-0375-0 2006-04-01T00:00:00Z
