Some Scientists Question Whether Quantum Computer Really Is Quantum

gbrumfiel writes "Last week, Google and NASA announced a partnership to buy a new quantum computer from Canadian firm D-Wave Systems. But NPR news reports that many scientists are still questioning whether new machine really is quantum. Long-time critic and computer scientist Scott Aaronson has a long post detailing the current state of affairs. At issue is whether the 512 quantum bits at the processor's core are 'entangled' together. Measuring that entanglement directly destroys it, so D-Wave has had a hard time convincing skeptics. As with all things quantum mechanical, the devil is in the details. Still it may not matter: D-Wave's machine appears to be far faster at solving certain kinds of problems (PDF), regardless of how it works."

Canadian Minister Mined Data To Target Email To Gay Voters

An anonymous reader writes "Has Immigration Minister Jason Kenney been emailing you? Maybe it's because you're gay.

For many who received an email from Citizenship and Immigration Minister Jason Kenney about gay refugees on Friday, the message raised one important question: How did he know I'm gay? The Conservatives have targeted written messages at minority communities in the past, most notably using direct mail lists to send out greetings to Jewish voters on religious holidays. Some recipients were alarmed by the prospect of the government assembling lists based on ethnicity or religious beliefs. Surely creating such a list will become easier ...

FCC filings, leaked roadmaps, and comments from RIM's top brass all pointed to the existence of an LTE-capable BlackBerry PlayBook -- the only question left was when the thing would finally launch.

RIM's LTE PlayBook will launch in Canada on August 9 (with support from a handful of Canadian carriers), where it will remain for the time being. The company hasn’t provided any specifics on when the 4G-capable tab will trickle into other markets, saying only that it will be available in “the coming months from carriers in the US, Europe, South Africa, Latin America and the Caribbean.”
