Physicists have produced the first-ever blueprints for a large-scale quantum computer that could herald a technological revolution in computing. If the industrial blueprint works, it could see the first super-fast quantum machine being built within a decade at a cost of tens of millions of pounds. Quantum computers have long been seen as the next stage in computing technology. Scientists believe this next generation machine could be many millions of times faster than contemporary computers. An international team the University of Sussex published the new blueprint in the academic journal Science Advances. "For many years, people said that it was completely impossible to construct an actual quantum computer. With our work we have not only shown that it can be done but now we are delivering a nuts and bolts construction plan to build an actual large-scale machine," lead scientist Winfried Hensinger said in a statement. The revolutionary potential of quantum computers lies in their
