Can we see the arrow of time? Algorithm can determine, with 80 percent accuracy, whether video is running forward or backward Date: June 20, 2014 Source: Massachusetts Institute of Technology ...

Climate models can be a million lines of code long and can take months to run on supercomputers. A new algorithm has dramatically shortened that time.

He worked on one of the first quantum circuits to run Shor’s algorithm in 2007: a table-top setup that sent photons travelling through the air rather tiny guides on a chip.
