Stories about: uncertainty principle

Quantum Computing Takes Giant Leap Heisenberg's uncertainty principle states that while trying to determine the exact position of a particle in a small region of space, the momentum of the respective particle becomes uncertain and vice versa, by determining the momentum of the particle its location becomes uncertain. This property of the nanoscal... 17 January 2008 10:02 GMT New Technique to Measure Nanoscale Distances By manipulating a few photons, a team of scientists from Griffith University Center for Quantum Dynamics, has managed to measure a difference in length less than one ten thousandth of a width of a human hair. The principle consists of sending a single photon through the sample which needs to be measured, which will a... 28 November 2007 10:45 GMT
