Title

Probing the Quantum-Classical Boundary Using Product Coherent States

Abstract

Several properties of quantum physics, such as uncertainty and entanglement, cannot be rigorously reconciled with classical physics. Heisenberg-style uncertainty relations pose an upper limit for the available information on the noncommuting observables of a system. In contrast, there is no quantum measurement uncertainty in classical physics. The closest we can get to the classical limit is by observing states with minimum and equal uncertainty, called coherent states. Entanglement necessitates a system with at least two parts (bipartite states). We discuss uncertainty and entanglement for selected bipartite coherent states, such as cat states.
