Quantum Entanglement: From paradoxes to reality
ABSTRACT :
This years Nobel prize in Physics has turned the spotlight on entanglement, a basic aspect of quantum physics that has excited debates from its very birth. A basic property of interacting quantum systems such as atoms in a molecule, it is associated with spooky action at a distance and other such mystifying popular formulations when the constituents are well separated entities. Its experimental verification took decades of painstaking work, and continues today in ever more sophisticated forms. These throw up challenges to our understanding of the quantum substratum in relation with common or classical experience. With the considerable advances in quantum information theory, quantum communication, and the making of primitive quantum computers, entanglement is viewed as a resource for crucial tasks such as teleportation. This talk will attempt to describe the apparent magic, controversy, and excitement around this quantity, especially through the lens of this years Nobel prize.
