Progress
At the moment there are no quantum computers doing useful work. Some manufacturers (like D-Wave) claim that they are but it's all just marketing talk. In fact, there's currently no quantum computer in existence which can perform calculations faster than classical ones, making the whole proposition that they are infinitely faster a theoretical conjecture.
Some have stated we should see so-called Quantum Supremacy (where quantum computers can do calculations which aren't feasible for classical ones) in the next couple of years. I'm not holding my breath.
