In summary, quantum computing is a type of computing technology that utilizes quantum-mechanical phenomena to perform operations on data. It is primarily based in physics, but also incorporates elements of computer science, mathematics, and engineering. The advantages of quantum computing include the ability to solve complex problems faster, more efficient energy usage, and improved security. However, there are challenges such as the fragility of quantum states and the high cost of building and maintaining quantum computers. Real-world applications of quantum computing include drug discovery, financial modeling, data encryption, and potential improvements in artificial intelligence and machine learning.
Good video
I've never seen any of his videos before; although I must have met him back when he was a PhD student (can't say I remember him though, this was many years ago)
