Quantum Computer Solves 2x2 Linear Equation

Rexy Tseng

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 equations 4x+3y=6 and 3x+2y=3—is the first proof that a quantum algorithm proposed in 2009, which promised exponential speed-up compared to one run on a normal CPU, can be implemented in the lab.
