Has the age of quantum computing arrived?

Its a mind-bending concept with the potential to change the world, and Canadian tech company D-Wave claims to have cracked the code

Ever since Charles Babbages conceptual, unrealised Analytical Engine in the 1830s, computer science has been trying very hard to race ahead of its time. Particularly over the last 75 years, there have been many astounding developments the first electronic programmable computer, the first integrated circuit computer, the first microprocessor. But the next anticipated step may be the most revolutionary of all.

Quantum computing is the technology that many scientists, entrepreneurs and big businesses expect to provide a, well, quantum leap into the future. If youve never heard of it theres a helpful video doing the social media rounds thats got a couple of million hits on YouTube. It features the Canadian prime minister, Justin Trudeau, detailing exactly what quantum computing means.

Trudeau was on a recent visit to thePerimeter Institute for TheoreticalPhysics in Waterloo, Ontario, one of the worlds leading centres for the study of the field. During a press conference there, a reporter asked him, half-jokingly, to explain quantum computing.

Quantum mechanics is a conceptually counterintuitive area of science that has baffled some of the finest minds as Albert Einstein said God does not play dice with the universe so its not something you expect to hear politicians holding forth on. Throw it into the context of computing and lets just say you could easily make Zac Goldsmith look like an expert on Bollywood. But Trudeau rose to the challenge and gave what many science observers thought was a textbook example of how to explain a complex idea in a simple way.
