Quantum Entanglement: Applications in Communication and Cryptography

Talk Timings: April 30, 2021 (Friday) 7.30 PM – 8.45 PM IST

Abstract: 

Quantum entanglement is a key phenomenon that separates the classical and quantum theories of information. In this talk, I will begin by introducing the notion of entanglement and discuss its applications, beginning with fundamental protocols like teleportation, super-dense coding, and the CHSH game. Then I will progress to more sophisticated topics like various communication capacities of quantum channels and highlight the role of entanglement in each of them. Key references include https://arxiv.org/abs/1106.1445 and https://arxiv.org/abs/2011.04672.
