| additional remarks | Quantum mechanical systems exhibit fundamentally different properties compared to classical systems. While the state of a classical particle can at any time be described by a set of well defined classical variables, quantum particles can be in superposition of different sates. If two or more particles are in a superposition such that the full state of the system can only be described by a joint superposition, then these particles are called entangled. The question whether the behaviour of entangled systems is determined by classical (local, realistic) variables was posed in a well-known paper in 1935 by Albert Einstein, Boris Podolsky, and Nathan Rosen (collectively “EPR”). Later, Bell formulated an inequality which allows to experimentally test whether the behaviour of entangled particles can be explained using such classical variables. Besides these fundamental physics questions, entanglement is the key element for applications of quantum physics such as quantum cryptography, teleportation or quantum computation. Furthermore, its characteristics can be used for a fundamental test of non-classical properties of quantum theory. Quantum tomography is an essential tool for many of these applications. In this lab course we will perform quantum state tomography on polarization-entangled photon pairs and violate Bell’s inequality. |
