The numerical simulation results show the quantumlimit of the quantum well width, beyond which will observe the resonant tunneling phenomena.

In this paper the phase properties of real laser field are calculated and analysed. Theresults are discussed in the "quantumlimit" and "classical limit" respectively.
A group of physicists in Spain has shown how to make a quantum measurement that overcomes a limit related to Werner Heisenberg's uncertainty principle.
