It is time to invest in the skills for quantum computing revolution

No wonder quantum computing has become the subject of such hype. Machines that harness the weirdness of quantum mechanics are so alien — and promise such massive theoretical leaps in performance — that it is easy to believe nothing will be the same again.

Full-scale quantum machines are probably many years away. But in the meantime, a “good enough” form of the technology — not revolutionary but promising significant advances for some applications — is on the horizon. The world will not change overnight, but development timetables already show practical quantum machines arriving much sooner than seemed likely only a short time ago.

Computers made up of quantum bits (or qubits) that can be in two states at once, or “entangled” to act in unison, could enable computers that are a million times or more faster than current machines. On a large enough scale, they may crack the world’s hardest problems.
