I&#8217;m in Oxford right now, for a Clay Institute workshop on <a href=\"http:\/\/www.claymath.org\/workshops\/CI\/\">New Insights into Computational Intractability<\/a>.\u00a0 The workshop is concurrent with three others, including one on <a href=\"http:\/\/www.claymath.org\/workshops\/NTP\/\">Number Theory and Physics<\/a> that includes an amplituhedron-related talk by Andrew Hodges.\u00a0 (Speaking of which, see <a href=\"https:\/\/scottaaronson.blog\/?p=1537#comment-88517\">here<\/a> for a small but non-parodic observation about expressing amplitudes as volumes of polytopes.)<\/p>\n<p>2. I was hoping to stay in the UK one more week, to attend the Newton Institute&#8217;s special semester on <a href=\"http:\/\/www.newton.ac.uk\/programmes\/MQI\/ws.html\">Mathematical Challenges in Quantum Information<\/a> over in Cambridge.\u00a0 But alas I had to cancel, since my diaper-changing services are needed in the other Cambridge.\u00a0 So, if anyone in Cambridge (or anywhere else in the United Kingdom) <em>really<\/em> wants to talk to me, come to Oxford this week!<\/p>\n<p>3. Back in June, Jens Eisert and three others <a href=\"http:\/\/arxiv.org\/abs\/1306.3995\">posted a preprint<\/a> claiming that the output of a BosonSampling device would be &#8220;indistinguishable from the uniform distribution&#8221; in various senses.\u00a0 Ever since then, people have emailing me, leaving comments on this blog, and cornering me at conferences to ask whether Alex Arkhipov and I had any response to these claims.\u00a0 OK, so just this weekend, we posted our own 41-page preprint, entitled <a href=\"http:\/\/eccc.hpi-web.de\/report\/2013\/135\/\">&#8220;BosonSampling Is Far From Uniform.&#8221;<\/a>\u00a0 I hope it suffices by way of reply!\u00a0 (Incidentally, this is also the paper I hinted at in a <a href=\"https:\/\/scottaaronson.blog\/?p=1502\">previous post<\/a>: the one where \u03c0<sup>2<\/sup>\/6 and the Euler-Mascheroni constant make cameo appearances.)\u00a0 To clarify, if we <em>just<\/em> wanted to answer the claims of the Eisert group, then I think a couple paragraphs would suffice for that (see, for example, <a href=\"http:\/\/www.scottaaronson.com\/talks\/optics-toronto.ppt\">these PowerPoint slides<\/a>).\u00a0 In our new paper, however, Alex and I take the opportunity to go further: we study lots of interesting questions about the statistical properties of Haar-random BosonSampling distributions, and about how one might test efficiently whether a claimed BosonSampling device worked, even with hundreds or thousands of photons.<\/p>\n<p>4. Also on the arXiv last night, there was a <a href=\"http:\/\/arxiv.org\/pdf\/1309.7495.pdf\">phenomenal survey about the quantum PCP conjecture<\/a> by Dorit Aharonov, Itai Arad, and my former postdoc Thomas Vidick (soon to be a professor at Caltech).\u00a0 I recommend reading it in the strongest possible terms, if you&#8217;d like to see how far people have come with this problem (but also, how far they still have to go) since my <a href=\"https:\/\/scottaaronson.blog\/?p=139\">&#8220;Quantum PCP Manifesto&#8221;<\/a> seven years ago.<\/p>\n<p>5. Christos Papadimitriou asked me to publicize that the deadline for early registration and hotel reservations for the upcoming FOCS in Berkeley is fast approaching!\u00a0 Indeed, it&#8217;s October 4 (three days from now).\u00a0 See <a href=\"http:\/\/www.eecs.berkeley.edu\/focs2013\/\">here<\/a> for details, and <a href=\"http:\/\/www.eecs.berkeley.edu\/focs2013\/travel_support\">here<\/a> for information about student travel support.\u00a0 (The links were down when I just tried them, but hopefully the server will be back up soon.)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Update (Oct. 3): OK, a sixth announcement.\u00a0 I just posted a question on CS Theory StackExchange, entitled Overarching reasons why problems are in P or BPP.\u00a0 If you have suggested additions or improvements to my rough list of &#8220;overarching reasons,&#8221; please post them over there &#8212; thanks! 1.
