After marvelling at this feat, Giuseppe Carleo of ETH Zurich in Switzerland thought it might be possible to build a similar machine-learning tool to crack one of the knottiest problems in quantum physics.<\/p>\n<p>Now, he has built just such a neural network \u2013 which could turn out to be a game changer in understanding quantum systems.<\/p>\n<p>Go is far more complex than chess, in that the number of possible positions on a Go board could exceed the number of atoms in the universe. That\u2019s why an approach based on brute-force calculation, while effective for chess, just doesn\u2019t work for Go.<\/p>\n<p>In that sense, Go resembles a classic problem in quantum physics: how to describe a quantum system that consists of many billions of atoms, all of which interact with each other according to complicated equations.<\/p>\n<p>But the weird rules of quantum mechanics mean we can\u2019t know a quantum particle\u2019s precise location at every point in time. Many quantum particles also have a property called \u201cspin\u201d, which can be either up or down. The number of spin-based states that a group of just 100 such particles could inhabit is almost a million trillion trillion (1030).<\/p>\n<p>The current record for simulating such a system, using our most powerful supercomputers, is 48 spins. Carleo estimates that even if we could turn the entire planet into a giant hard drive, we would still only be able to do these calculations for 100 spins at most.<\/p>\n<p>That\u2019s where artificial neural networks can help. Give such a network the rules of Go and it will figure out the optimal strategy to win the game. So perhaps it could do the same for quantum systems.<\/p>\n<figure >\n<blockquote data-animation-role=\"quote\" data-animation-override><p>     <span>&#8220;<\/span>Neural networks are very good at generalising, so they typically only need a limited amount of information to infer much more from that.<span>&#8221;<\/span>   <\/blockquote><figcaption class=\"source\">&mdash; Giuseppe Carleo<\/figcaption><\/figure>\n<p>Feed a neural network a few pictures of Carleo, for example, and it will soon be able to recognise him in new pictures it has never \u201cseen\u201d before.<\/p>\n<figure >\n<blockquote data-animation-role=\"quote\" data-animation-override><p>     <span>&#8220;<\/span>It\u2019s incredibly cool &#8230; given the success of deep learning in pretty much every imaginable application domain, it\u2019s a natural idea to try it for quantum many-body physics, but as far as I know this is the first time someone did.
