"Quantum computing could someday supercharge artificial intelligence, accelerate drug discovery, and even reduce traffic jams. But existing quantum computers, which have only a modest, if any, advantage over their classical brethren, are expensive, finicky beasts. Even if you could afford the US $15 million to buy a D-Wave 2000Q quantum annealer [PDF], for example, you would need experts to maintain the ultracold operating conditions its processor requires.
Until today, that is, when Canadian startup D-Wave Systems Inc. launched a real-time online quantum computing environment called Leap. Leap is the latest addition to the quantum cloud—services that virtualize quantum computing for almost anyone with a computer and a broadband connection to use." Read the article in IEEE Specturm.
