IOS DVS Lecture 3 — Hyperentanglement: When One Degree of Freedom isn’t Enough

Distinguished Visiting Scientists program of the Institute for Optical Sciences

Quantum systems can often be entangled in one of various degrees of freedom, and it is now known that they can be simultaneously entangled in several of these at once, a phenomenon known as "hyperentanglement". I will discuss methods to produce and characterize such states, as well as several recent applications, including high-capacity super dense quantum coding, remote entangled state preparation, and ultra-high speed quantum cryptography.
