(TechCrunch) Quantum computers will be useful in advancing solutions to challenges in diverse fields such as energy, finance, healthcare, aerospace, among others. Their capabilities will help us cure diseases, improve global financial markets, detangle traffic, combat climate change, and more. Quantum computing’s purpose is to aid and extend the abilities of classical computing. Quantum computers will perform certain tasks much more efficiently than classical computers, providing us with a new tool for specific applications.
One principle may help readers get their arms around the difference between classical computing and quantum computing. Classical computers are binary. That is, they depend on the fact that every bit can exist only in one of two states, either 0 or 1. Schrödinger’s cat merely illustrated that subatomic particles could exhibit innumerable states at the same time.
