Quantum Supremacy What is it and what does it mean

Google is working on its first demonstration of quantum supremacy, in which a quantum computer outperforms a conventional computer. In this video I explain what quantum computers are good for, what quantum supremacy is and what it will mean. The current approaches to quantum computing are scientifically interesting, but the challenge to scaling them up to practically useful applications is formidable.
