Werner Heisenberg's 'Uncertainty Principle'(1927) is a fundamental concept in quantum physics, basically saying you can be increasingly accurate in position or momentum (mass X velocity), but not both(1). This can be an important feature rather than a defect in something like quantum cryptography, where information is transmitted in the form of quantum states such as the polarization of particles of light.A group of scientists from LMU and the ETH in Zurich say they have shown that position and momentum can be predicted more precisely than Heisenberg's Uncertainty Principle states - if the recipient makes use of a quantum memory that employs ions or atoms.read more
