An imaginary experiment to understand the elements of Q-Mechanics

In this section, we will try to go deeper by providing an imaginary experiment to introduce Q-Mechanics. This experiment’s elements are similar to Young’s experiment: a wall with two slits and a screen on the back. Throughout the chapter, step by step, we will address more elements that will help you set up the experiment and understand the paradoxes of Q-Mechanics.

Suppose we shoot a photon toward the two slits shown in the following diagram. We will think of the photons as small marbles.

Step 1: superposition

Let’s start by shooting marbles that are a normal size. Each time a marble is shot, it will likely move toward the slit and pass through it. So, let’s assume that at the end of the first round, the result will be that most of the marbles will hit the screen in a straight line behind the slits:
