What can quantum computers do that ordinary computers can't?.What would a quantum computer be like in reality?.Quantum + computing = quantum computing.
#HOW DO QUANTUM NUMBERS HELP SCIENTISTS UNDERSTAND PLUS#
On the plus side, this opens up the possibility of faster computers, but the drawback is the greater complexity of designing computers that can operate in the weird world of quantum physics. Photo: Quantum computing means storing and processing information using individual atoms, ions, electrons, or photons. Quantum computing and how does it work? Let's take a closer look! Physics, where the "classical," sensible, everyday laws of physics no longer apply. That quantum computing is hugely more complex than traditionalĬomputing and operates in the Alice in Wonderland world of quantum Entering the realm ofĪtoms opens up powerful new possibilities in the shape of quantumĬomputing, with processors that could work millions of timesįaster than the ones we use today. That are smaller and more powerful than today's, we'll soon need toĭo our computing in a radically different way. They'll soon be as small as individual atoms. One problem is that the basic switching and memory units ofĬomputers, known as transistors, are now approaching the point where That are beyond the reach of even the world's most powerfulĬomputers-and there's no guarantee we'll ever be able to tackle Such amazing advances, there are still plenty of complex problems
How can you get more and more out of less and less? The smaller computers get, the more powerful they seem to become: there's more number-crunching ability in a 21st-century cellphone than you'd have found in a room-sized, military computer 50 years ago.
