You ’d think quantum computer exist in to a great extent - guarded labs , with many Isle of Man in whitened suits manning control stations filled with unfathomable screen and charts . in reality , they exist in a small cupboard in England ’s West Country .
Tom Scotttook a hitch of Bristol ’s Quantum Photonics lab to look at their quantum computer . Far from glamourous , it ’s really just a small fleck sitting on a desk , using photons rather than electricity to make quantum bits . As the university explain :
Photons can also step in with each other and share their quantum state . This quantum phenomenon is known as entanglement and was described by Albert Einstein as “ a spooky action at a aloofness ” . The interaction continue even when the particles are no longer near each other and is hard to understand in terms of our everyday world . An activeness on one entangled quantum mote will result in an instantaneous action on the other embroiled particle conserve the laws of energy and momentum . But , you may not insure which way you will regulate them so we rely on statistical probabilities to narrate us what the most probable result of an activeness is .
Best of all , the university has asimulatoron its site — and if you germinate a cool experimentation in the simulator , they ’ll permit you remote - mastery a existent computer . All without have to get up , or put trouser on . That ’s what I call skill . [ YouTube ]
