INTRODUCTION TO THE QUANTUM TELEPORTATION


In order to speak of Quantum Teleportation it is necessary to take into account the wave and corpuscular nature of electromagnetic radiation and matter. That is to say “wave-particle duality” for light and matter.

The wave and corpuscular nature of particles is related by the Heisenberg’s Uncertainty Principle; this principle was formulated by the German scientist Werner Heisenberg, in 1927, and states that:

if the uncertainty Δx on the position x of a particle is very little,

the uncertainty Δp on the momentum p is large and vice versa.

Representation of the Heisenberg’s Uncertainty Principle:

The math expression of the principle is:

Δx·Δp ≥ h/4π

or

Δx·Δp ≥ ћ/2

According to the Heisenberg’s Uncertainty Principle we can say that it is impossible to know simultaneously and with accuracy the momentum and the position of a particle.

The same uncertainty affects the simultaneous measurement of energy E and time t:

ΔE·Δt ≥ ћ/2

This means that “in a very short time the energy is not defined”.

In other words, “the product of the uncertainties of two simultaneous measurements cannot be less than a given constant”.
