Galrahn making lots of sense on the UK nuclear deterrent
A Bell inequality has been violated in a system of Josephson phase qubits and the D-Wave crowd has implemented a “novel rf-SQUID flux qubit that is robust against fabrication variations in Josephson junction critical currents and device inductance” (just when it seemed like Dave Wineland’s group at NIST suddenly had a monopoly on experimental advances in quantum computing, superconducting qubits start getting entangled all over the place)
The Annals of Probability has a couple of memorial articles on Joe Doob (available on the arxiv here and here)
update:
“[Iran has] cheated three times,” one senior administration official with access to the intelligence said of the Iranians late on Thursday evening. “And they have now been caught three times.”
The official was referring to information unearthed by an Iranian dissident group that led to the discovery of the underground plant at Natanz in 2002, and evidence developed two years ago — after Iran’s computer networks were pierced by American intelligence agencies — that the country had secretly sought to design a nuclear warhead. American officials believe that effort was halted in late 2003.
