However, while Google's achievements have been noted for advancing the field, experts say that quantum computing still has no real-world uses — yet. Proponents of quantum computing claim it will be able to solve problems that current computers can't. Quantum computing uses quantum bits or qubits which can be zero, one or something in between. This is a very important milestone for quantum computers." But despite optimism that quantum computing could one day change the world — or at least computers' role in it — experts in the field have suggested that Google's quantum computing breakthrough is still lacking in real-world uses.
