Conversely if a product is a dismal failure it&#8217;s usually guaranteed that it&#8217;ll get a whole bunch of the wrong type of attention, especially with the Internet&#8217;s bent towards\u00a0schadenfreude. With that in mind it made me wonder why I hadn&#8217;t heard more about D-Wave since <a href=\"https:\/\/therefinedgeek.com.au\/index.php\/2012\/04\/26\/another-quantum-leap-forward-for-computing\/\" target=\"_blank\">I last wrote about them<\/a> around this time last year. Especially considering that Lockheed Martin had bought one of their D-Wave One systems a year prior to that.<\/p>\n<p>Turns out they probably don&#8217;t really need the press <a href=\"http:\/\/www.vancouversun.com\/business\/technology\/Quantum+computer+developed+Metro+Vancouver+wins+over\/8202950\/story.html\" target=\"_blank\">as they&#8217;re doing just fine<\/a>:<\/p>\n<blockquote><p>VANCOUVER \u2014 When the world\u2019s largest defence contractor reportedly paid $10 million for a superfast quantum computer, the Burnaby, B.C., company that built it earned a huge vote of confidence.<\/p>\n<p>Two years after Lockheed Martin acquired the first commercially viable quantum computer from D-Wave Systems, the American aerospace and technology giant is once again throwing its weight behind a technology many thought was still the stuff of science fiction.<\/p><\/blockquote>\n<p>You&#8217;d be forgiven for thinking that this was just old news resurfacing 2 years later but it isn&#8217;t as Lockheed Martin just purchased a D-Wave 2, their latest and greatest quantum computing offering. Details are a little scant as to what is actually in their latest system but going off <a href=\"http:\/\/www.dwavesys.com\/en\/images\/tut-hardware-roses-law.jpg\" target=\"_blank\">their product road map<\/a>\u00a0it&#8217;s likely to be some variant of their <a href=\"http:\/\/dwave.wordpress.com\/2011\/12\/01\/vesuvius-a-closer-look-512-qubit-processor-gallery\/\" target=\"_blank\">Vesuvius chip<\/a> which contains 512 qubits. That&#8217;s 4 times the amount of qubits in their previous system which would make it exceptionally more powerful and all for the same cost as the first unit they sold.<\/p>\n<p><a href=\"https:\/\/i0.wp.com\/therefinedgeek.com.au\/wp-content\/uploads\/2013\/04\/D-Wave-Quantum-Computing-Chip.jpg?ssl=1\"><img data-recalc-dims=\"1\" decoding=\"async\" class=\"aligncenter size-large wp-image-4928\" alt=\"D-Wave Quantum Computing Chip\" src=\"https:\/\/i0.wp.com\/therefinedgeek.com.au\/wp-content\/uploads\/2013\/04\/D-Wave-Quantum-Computing-Chip.jpg?resize=600%2C450&#038;ssl=1\" width=\"600\" height=\"450\" srcset=\"https:\/\/i0.wp.com\/therefinedgeek.com.au\/wp-content\/uploads\/2013\/04\/D-Wave-Quantum-Computing-Chip.jpg?resize=600%2C450&amp;ssl=1 600w, https:\/\/i0.wp.com\/therefinedgeek.com.au\/wp-content\/uploads\/2013\/04\/D-Wave-Quantum-Computing-Chip.jpg?resize=300%2C225&amp;ssl=1 300w, https:\/\/i0.wp.com\/therefinedgeek.com.au\/wp-content\/uploads\/2013\/04\/D-Wave-Quantum-Computing-Chip.jpg?w=700&amp;ssl=1 700w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/a><\/p>\n<p>In my quest to try and find a little more information about their new system I stumbled across <a href=\"http:\/\/www.dwavesys.com\/en\/dev-tutorial-hardware.html\" target=\"_blank\">this page which digs into the underlying architecture of the D-Wave One\/Two systems<\/a>. Now back when I first wrote about D-Wave they weren&#8217;t exactly forthcoming with this kind of information which was what drew them a considerable amount of criticism but since then a lot of their loudest critics have renounced their positions. Interestingly though, and feel free to correct me if I&#8217;m interpreting this wrong, whilst they indeed claim to have produced a functioning qubit they haven&#8217;t managed to entangle several of them together. Whilst this doesn&#8217;t make their system useless, single qubits daisy chained together will still be useful for some specific functions, it does mean that the exponential scaling doesn&#8217;t really apply to D-Wave&#8217;s style of quantum computers. I could be wrong about this but their explanation only mentions entanglement-like properties in the qubit section with their interconnecting grids only being used to &#8220;exchange information&#8221;, not to provide multi-qubit entanglement.<\/p>\n<p>That doesn&#8217;t make it any less cool however as I&#8217;m sure as they continue to scale up their processors they&#8217;ll eventually start entangling more bits together which will increase their computational power exponentially. We won&#8217;t see consumer level processors using technology like this for a long time though as they&#8217;re akin to CUDA units on graphics cards, highly specialized computational units that excel in their task and not so much in general computing. Still D-Wave&#8217;s systems signal the beginning of the quantum computing era and that means its only a matter of time before we see them everywhere.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When a technology company doesn&#8217;t get a whole lot of press it usually means one of two things: the first is that it isn&#8217;t that&#8230;<\/p>\n","protected":false},"author":2,"featured_media":4928,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[13,4],"tags":[2298,4289,2299,2297,2301],"class_list":["post-4927","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-science","category-tech","tag-d-wave","tag-entanglement","tag-lockheed-martin","tag-quantum-computing","tag-qubit"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/therefinedgeek.com.au\/wp-content\/uploads\/2013\/04\/D-Wave-Quantum-Computing-Chip.jpg?fit=700%2C525&ssl=1","jetpack_shortlink":"https:\/\/wp.me\/ppBqt-1ht","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/posts\/4927","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/comments?post=4927"}],"version-history":[{"count":0,"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/posts\/4927\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/media\/4928"}],"wp:attachment":[{"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/media?parent=4927"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/categories?post=4927"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therefinedgeek.com.au\/index.php\/wp-json\/wp\/v2\/tags?post=4927"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
