UK Scientists Make Step Toward Quantum Computer—Humankind Inches Closer To Infinite Computing
Nature reports that Scientists in the UK have found a way to use light-emitting diodes (LEDs) to work as switches in a possible quantum computing system.
A true quantum computer could have infinite computational abilities—or at least be exponentially more powerful than today’s computers.
Mark Stevenson and his team at Toshiba Research Europe in Cambridge, England, found a way to trap photons using LEDs. Photons are subatomic particles that compose light. By trapping them, engineers could control on a sub-atomic scale the traditional on-off switch of a computer. The quantum nature of the photon means that a computer using this method could potentially explore all possible computational and decision paths simultaneously.
Could this discovery be the start of Kurzweil’s singularity event?
From the article:
When the researchers supply the LED with electric current, two electrons hop into two positively charged ‘holes’ in the quantum dot’s lattice, releasing energy in the form of a photon pair. Crucially, the nature of this process means that the polarization of one generated photon is determined by the other, so the pair is entangled.
There is a catch to Stevenson’s current method, however. Only one in 100 diodes actually entangle the light, and the whole system only works at temperatures of 5 kelvin (or -268 Celsius).
