Quantum computing is the use of fundamental ideas from quantum mechanics to perform computations on special devices called quantum computers. Quantum systems can process information in ways that classical computers can't. For example, they can explore multiple possibilities at once. This capability is thanks to concepts like superposition, entanglement, and interference, which you'll explore soon.

Quantum mechanics is unquestionably a robust and successful theory - so far, all its predictions have held, and scientists can build powerful technologies based on it. Yet, understanding what it tells us about the nature of reality and how we experience it has proven tricky. Physicists and philosophers have been grappling with it for a century, ironing out some of the early ambiguities, but some conceptual problems remain.
