So I opened my freshly delivered copy of this month’s Physics World and began to mull over the articles whilst enjoying a Kitkat. On the first page I found an piece about Ion Trap quantum computing proclaiming that “Researchers in the US claim to have created the first small scale device that can perform all the steps needed for large-scale quantum computation” referring to NIST’s latest ion trap chip.
You can read about it here:
Scalable ion traps for quantum information processing
Here is the PhysicsWorld web version of the article:
Tiny device is first complete ‘quantum computer’
Haven’t superconducting flux/charge qubits have been able to do this for ages – what’s all this ‘first’ business? Besides, didn’t Yale do something similar a few months back? Oh no, wait a minute, they actually ran an algorithm…
And that’s without even considering the advances in AQC, hmmm.
Anyway, that didn’t bother me too much. But then the article goes on to say:
“The implication was that quantum computers could operate at ultra-high speeds, which could be applied to solving complex problems like cracking some of today’s most widely used encryption codes.”
Is that the BEST application you can think of to run on a QC? Really? Come on… Get creative! Who cares about cracking RSA anyway? They’ll just keep adding more digits 😉
In fairness the magazine also had quite a nice article about the violation of Bell’s inequalities and some of the potential loopholes in those experiments. Which made me happier.
