Big step forward towards Quantum Computers

Entangled photons available on tap
18:00 02 June 2010 by Marcus Chown

The creation of an "entanglement gun" brings the prospect of a light-based quantum computer a step closer. The ability of entangled photons to spin in two different senses will allow quantum computers to encode a 0 and a 1 simultaneously, allowing even a small quantum computer to outperform the fastest supercomputer for some tasks.

A team from Toshiba Research Europe in Cambridge, UK, and the University of Cambridge made the entanglement gun from a "quantum dot", formed by a patch of indium arsenide semiconductor no more than 10 nanometres across. When an 80-megahertz alternating current passed through the quantum dot it trapped two negatively charged electrons and two positive "holes". On each cycle of the current, the electrons and holes combined to eject a pair of entangled photons.

If Quantum Computers ever become a reality, does anyone think the government will attempt to restrict the computing power the average citizen can have access to? Sort of like guns today?

              - yeah. It is.  agent46   Jun-09-10 01:15 PM   #35 
     - If you're so awful  Confusious   Jun-08-10 04:10 PM   #18 
        - this is where you lack important information. posthuman is not  Soylent Brice   Jun-10-10 07:15 AM   #36

  - I've always suspected the government  Ratty   Jun-08-10 01:20 PM   #10 
  - Quantum computers are still too conceptual. 1 or 2 qubits doesn't cut it for me. nt  LLStarks   Jun-08-10 01:47 PM   #12 
  - Yes, but it's all been conceptual up to this point.  FLPanhandle   Jun-08-10 02:20 PM   #14 
  - Ah well. It was nice having cryptography the government can't crack for a couple decades.  Commie Pinko Dirtbag   Jun-08-10 04:45 PM   #19 
  - Back to one-time pads! (nt)  Posteritatis   Jun-08-10 04:50 PM   #21 
  - You will also be able to crack any code any government uses  FLPanhandle   Jun-08-10 05:24 PM   #23 
  - Link to original Nature article for the curious  entanglement   Jun-08-10 05:29 PM   #24 
  - If they were going to, they would have done it before now.  Old Troop   Jun-08-10 05:54 PM   #26 
     - They've tried a few times with things like encryption legislation  Posteritatis   Jun-09-10 08:23 AM   #29 
        - Which is why I think when the average person can decrypt any government code, the tech will banned  FLPanhandle   Jun-09-10 08:36 AM   #30 
           - It'd be nearly impossible to enforce these days  Posteritatis   Jun-09-10 09:02 AM   #31
