Link Think

Hi bloggers,

I am starting a new feature where I am going to share interesting web-links. mostly related to Science. These may include news articles, popular physics essays or even blog pieces written by the vibrant community of scientist bloggers. Here is the first installment.

1. John Preskill's nice piece, where he summarizes the different viewpoints prevalent in the scientific communities on the "Firewall Paradox", recently put forward  by the AMPS team (the acronym draws from the initials of the four researchers involved this work --- Ahmed Almheiri, Donald Marolf, and James Sully, from the University of California, Santa Barbara, and Dr. Polchinski of the KITP, Santa Barbara.) It boils down to a revisitation of the black hole information paradox, over which John Preskill had won a bet against Stephen Hawking in 2004. For an accessible commnetary, correct in essentials, see the New York times article here.

2. Scott Aaronson on NSA's recent claim about their groundbreaking cryptanalytic capabilities. He entertainingly alludes to the possibility of NSA acquiring a quantum computer from D-wave - a company of whose claims he is the self-proclaimed Chief Skeptic!

3. A slightly old, but really well written commentary in Quanta Magazine, on a recent theoretical breakthrough which shows how an untrusted or noisy quantum system may be employed for secure quantum key distribution.
