Scientists set quantum speed limit - The flip side of Heisenbergs uncertainty principle, the energy time uncertainty principle, establishes a speed limit for transitions between two states. Physical chemists have now proved this principle for transitions between states that are not entirely distinct, allowing the calculation of speed limits for processes such as quantum computing and tunneling. The proof puts on sound footing a relationship that most physicists use dai... ow.ly/2TKj8A
