Quantum memory may topple Heisenberg's uncertainty principle

A quantum memory may be all scientists need to beat the limit of Heisenberg's uncertainty principle, according to a paper published in Nature Physics. According to a group of researchers, maximally entangling a particle with a quantum memory and measuring one of the particle's variables, like its position, should snap the quantum memory in a corresponding state, which could then be measured. This would allow them to do something long thought verboten by the laws of physics: figure out the state of certain pairs of variables at the exact same time with an unprecedented amount of certainty. via Quantum memory may topple Heisenberg's uncertainty principle.
