This video is hosted by Associate Professor Andrea Morello from the School of Engineering (University of New South Wales, Australia), who is able to give a very clear explanation of quantum entanglement. Morello shows that the best way to explain it is to first explore what it’s not: classical correlation. And this can be done using a simple piece of paper and red and blue text.
The quantum entanglement phenomenon has met with skepticism throughout the years. Even Albert Einstein was not entirely sure about it - which caused him to speak the frequently quoted words “spooky action at a distance”. Einstein’s hesitation certainly hasn’t stopped the phenomenon from being observed through many experiments, and becoming central to most work in quantum mechanics.
Essentially, quantum entanglement suggests that acting on a particle here, can instantly influence a particle far away. This is often described as theoretical teleportation. It has huge implications for quantum mechanics, quantum communication and quantum computing.
