<p>According to Physics World researchers at the University of Bristol, UK have made a prototype optical quantum computer chip and used it to perform a mathematical calculation. The device consists of tiny silica waveguides on a silicon chip and carries out a version of the quantum calculation known as Shor's algorithm. The result is an important step towards making practical, real-world quantum computers.</p>
