Black Hole Information Loss Paradox Solution Proposed 252

Anuborn Satirak writes to tell us that Physicists from Case Western Reserve University claim to have cracked the black hole information loss paradox that has puzzled physicists for the past 40 years. "The physicists are quick to assure astronomers and astrophysicists that what is observed in gravity pulling masses together still holds true, but what is controversial about the new finding is that 'from an external viewer's point it takes an infinite amount of time to form an event horizon and that the clock for the objects falling into the black hole appears to slow down to zero,' said Krauss, director of Case's Center for Education and Research in Cosmology."

Submission + - The Ability to "controllably Couple qubits"

Timogen writes: While large-scale quantum computers remain in the domain of science fiction, a joint team from Japan announced Thursday that it has been able to take a small but crucial step in pursuit of this advanced goal. http://www.wired.com/science/discoveries/news/2007 /05/quantumcoupling NEC, the Institute of Physical and Chemical Research, or RIKEN, and the Japan Science and Technology Agency, published a paper in the May 4 issue of the journal Science, outlining the ability to "controllably couple qubits." In classical computer science, bits — or binary digits — hold data encoded as ones and zeros. In quantum computing, data is measured in qubits, or quantum bits. As such, a qubit can have three possible states — one, zero or a "superposition" of one and zero. This unique property theoretically makes quantum computing able to solve large-scale calculations that would dwarf today's supercomputers. But qubits in isolation are not very useful. It's only when they can be connected to one another that large-scale processing becomes possible.
