First Experimental Proof For Super-Fast Quantum Algorithm Published

It's only three lines of simple math for a human, but a small victory for a quantum computer. Researchers in China report in Physical Review Letters that they can solve two linear equations by manipulating four entangled photons. Their demonstration-the rough equivalent of solving for x and y in the...
