Defeating Heisenberg's Uncertainty Principle

eldavojohn writes "As we strive closer and closer to quantum computing, physics may need to be improved. A paper released in Nature Physics suggests that the limit defined by Heisenberg's Uncertainty Principle can be beaten with quantum memory. From the article, 'The cadre of scientists behind the current paper realized that, by using the process of entanglement, it would be possible to essentially use two particles to figure out the complete state of one. They might even be able to measure incompatible variables like position and momentum. The measurements might not be perfectly precise, but the process could allow them to beat the limit of the uncertainty principle.' Will we find out that Heisenberg was shortsighted in limiting the power of quantum physics or will the scientists be surprised to find that such a theoretical scenario — once conducted — performs unexpectedly in Heisenberg's favor?"

Slightly OT: did anyone see top-gear yesterday?

[Vectormatic]

Yesterday on the BBC during top-gear there was a review of the new Ferrari 458

Apparently one of the LCD displays in the cockpit functions as EITHER the speedo, or the satnav. So you either know where you are, or how fast you are going.

Looks like the Ferrari engineer in charge of the 458 cockpit was a Heisenberg fan :P
