Entanglement

Quantum Mechanics dramatically illustrates the differences between classical and quantum conceptions of Nature. The most mysterious feature of quantum realm is quantum correlations which have no classical counterparts. Quantum correlation is not the one but the trait characteristics of quantum mechanics. It is at the heart of almost all quantum paradoxes. What is then the nature of these correlations? According to Bell's Theorem, one cannot construct a local realistic hidden-variable theory that can reproduce all the statistical predictions of quantum mechanics for a two particle singlet state. So, we are still facing the crucial problem of whether correlations resulting from the entanglement of two spatially separated particles are an essential characteristic of microphysical reality. These are the main conceptual issues of Quantum Physics that are investigated in Dr. Shafiee's research group.
