To: Jeffrey Epsteinueevacation©gmailcom] From: Seth Lloyd Sent Sat 9/7/2013 2:19:31 PM Subject: Hey! Dear Jeffrey, Just checking in to see how you are doing. Things here are good: John Preskill and I just posted a paper on black hole evaporation to try to resolve the so-called 'firewall' paradox, and it is catching people's notice (I attach it). Plus I've been doing a bunch of work on 'big quantum data': it turns out that a quantum computer can find patterns in a data set with N pieces of data in time log N. So if you wanted to find patterns in the data set consisting of all the genomes of all the people on earth (ca. 10/%20 bits), you could do it on a quantum computer with only a few hundred qubits. In addition, I have a remarkable and pleasant coincidence to report. David Grosofs nephew Isaac is in my freshman seminar at MIT. He is super-smart and nerdy and fun to talk with -- the apple does not fall far from the orchard. Hoping our paths cross soon. Let me know if you're going to be up in Cambridge any time. Yours, Seth EFTA_R1_00428218 EFTA01956912
