## 物理代写|光学作业代写Optics代考|Heisenberg uncertainty

The Heisenberg uncertainty principle [16] has to do with the joint statistical distribution of the measured values of two variables corresponding to repeated measurements of identically prepared systems [89], and applies to the simultaneous measurements of two dynamic variables whose quantum operators do not commute in a given set of state wave functions, the variables being incompatible observables.

The principle of uncertainty does not preclude the existence of welldefined numerical values for either variable [16]. Limited information about one variable is associated with a variance in the measured values, with more information being available about the other variable. Measurements yield precise instantaneous values – within the constraints of the equipment – by “collapsing” the system’s wave function into a specific value [16]. A quantum “spread” implies that measurements on identically prepared systems do not return identical results because of system-related fluctuations such as spontaneous emission, time-varying losses, temperature variations, background radiation, etc.

One should not confuse prediction with measurements. It is the measured values that come into play when plotting the joint distribution of two observable physical variables. A measurement of only one variable will still have its own variance of values but it is not subject to the Heisenberg uncertainty principle, because the physical system is not disturbed by the measurement of another variable. One can easily measure a well-defined eigenvalue of an operator [16] at a given time.

In free space, the degree of coherence of an optical monochromatic wave would be characterized by the statistical phase variance of the ergodic evolution of the wavefront phases. Their measured statistical distribution -if detected in conjunction with another observable physical quantity or variable – will be subject to the Heisenberg uncertainty principle characterizing statistical measurements of ensembles. However, each instantaneous wave front has, possibly, a time-varying, and – as a result of interacting with the dielectric medium which collapses the wave function a well-defined phase which will be involved in the optically linear parametric interactions in a dielectric medium $\left[\begin{array}{ll}3 & -6\end{array}\right]$.

Two dynamic number states – derived in the previous Section $3.3$ – copropagating through a dielectric medium will couple photons from one state to the other depending on the relative phase between the two waves. This process, repeatedly, will eliminate optical waves whose phases diverge substantially from the phase of the surviving wave which will dominate the output of a lasing cavity.
