# Is the Lotto Ball Machine a Quantum computer of sorts?

Quantum Computing is my latest interest and i’m trying to learn as much as possible about it.

The Qubits have me a bit phased out, trying to visualize them. Trying to scale it up to a real life size in my mind to better visualize it.

And the Lotto machine popped into my mind.

Maybe not as exactly Qubits but as a whole quantum computer of sorts.

You have for example 42 numbered balls stored before the draw in a predefined position, the input.

Dropped into the rotating drum the actual computer.

The balls go into superposition and entanglement bouncing off each other. You slow down the drum for an instant and take a measurement allowing a ball to drop out of the opening at the bottom. A portion of the output. You continue running your computer and repeating the measuring until you get your 5 or 6 winning numbers, the final output.

Just wondering is it a quantum computer or quantum system?

As far as we know, all physical systems behave in a way that can be described using quantum mechanics. However, the Lotto machine works at a scale where quantum effects do not play a role. You can view it as a classical system with an enormous state space, in which the vast majority of states do not show any ordering of the balls. Thus, the drawing of a single ball appears to yield a randomly-selected number.

What you have described is a random number generator, which is a useful (and commercially relevant) device. However, it’s not a computer, since the essence of computation is being able to obtain a predictable output from a known input.
