Making quantum systems computable

September 28, 2023

Now, when I shake my box and open it, I see that the die shows a one, for example. The probability that your die also shows one, or any other number, is also one sixth. This fundamental property of quantum physics paves the road to very concrete applications: for example, quantum teleportation. Quantum teleportation uses entanglement to transmit information from one place to another. If you now increase the number of quantum systems, the entanglement properties become increasingly complex.

Can you try giving an explanation anyway?
Imagine that I have two dice. I put each one in a separate box. You get one box, and I keep the other. Now, when I shake my box and open it, I see that the die shows a one, for example. The probability of this happening is one sixth. The probability that your die also shows one, or any other number, is also one sixth. But if the dice are entangled, things are different. When something happens to one die, it affects the other. If my die, which is entangled with yours, shows the number one, I can be certain that your die will also show a one. This fundamental property of quantum physics paves the road to very concrete applications: for example, quantum teleportation. Anton Zeilinger received the Nobel Prize in 2022 for this and other applications of quantum mechanics. Quantum teleportation uses entanglement to transmit information from one place to another. If you now increase the number of quantum systems, the entanglement properties become increasingly complex.
