Isn't getting a qubit into a coherent state in the first place one of the biggest hurdles in quantum computing? The headline seems to be putting the cart before the horse saying we'll get "affordable" quantum computers thanks to this.

I'm not knocking the scientists efforts, I don't doubt the worth of their discovery, but if science news articles were true we'd have flying solar powered cars with batteries the size of a cell phone that can recharge in under a minute.
