چکیده

1.2 REMARK ON INTERPRETATIONS OF THE SHANNON ENTROPY There are standard ways to interpret the Shannon entropy. For instance, the quantity H(p) can be viewed as a measure of the amount of uncertainty in a random experiment described by the probability mass function p, or as a measure of the amount of information one gains by learning the value of such an experiment. Indeed, it is possible to start with simple axioms for what a measure of uncertainty or information should satisfy, and to derive from these axioms that such a measure must be equivalent to the Shannon entropy.

Generation of Fiber - Coupled , Nondegenerate , Polarization - Entangled Photons for Quantum

The production of polarization-entangled photon pairs from spontaneous parametric downconversion (SPDC) enables many applications of quantum information processing. In this thesis, we use type-0 phase-matched downconversion of pump photons from a 532 nm continuous-wave laser to generate 798 nm signal and 1.6 tim idler photon pairs in periodically-poled, congruent lithium niobate (PPLN). Differe...
