If you’re one of the many people who doesn’t really comprehend quantum entanglement, the recent episode of the University of New South Wales (UNSW) eLearning’s Quantum Around You will probably change that. eLearning’s Quantum Around You is hosted by Associate Professor Andrea Morello from the School of Engineering, this is one of the perfect descriptions of the phenomenon we’ve ever seen. And if you already understood quantum entanglement, then definitely, you win. Even Albert Einstein was doubtful about certain properties of quantum mechanics - precisely, this unusual type of connection called entanglement, which he called "spooky action at a distance".
But this hasn’t stopped quantum entanglement from being observed through several experiments, and becoming vital to most work in quantum mechanics. Fundamentally quantum entanglement proposes that acting on a particle here can rapidly effect a particle far away, something that is frequently called as theoretical teleportation.
And the implications are HUGE for quantum mechanics and also for quantum computing. But if it’s so complex that not even Einstein could get his head around it, how do you describe it on YouTube? As Morello demonstrates in this fantastic video, the best way is to first describe what it’s not: classical correlation. Watch the full episode belowand have your mind expanded.
