Hi, can you explain what quantum computers are and why companies are investing in their creation? In particular, I would like to understand the differences between a normal computer and a quantum computer and what this can bring to the world.
Normal computers represent data as bits which hold a single possible value, 0 or 1. Everything can be represented with these two states. Quantum computers represent data as qubits, they hold both values simultaneously and then "resolve" when it is necessary. In this way, things like encryption or other hard problems in computer science become trivial. The combination of quantum computing and AI will likely change the way every human task happens over the next 10 years.
