String theory entangled

Equations can be retooled to describe a strange quantum effect

By Laura Sanders, 12:56 PM September 3, 2010

Physicists looking for a way to test their theory about strings might make more progress if they tangle them up.

String theory — equations that aspire to explain all of nature’s particles and forces — has extended its reach to the strange quantum behavior known as entanglement, physicists report September 2 in Physical Review Letters. Repurposing string theory mathematics allowed physicists to solve a hard problem involving entanglement, a strange feature at the heart of quantum mechanics...
