Content Data

This page contains data entry 89527 from the Axioma AXP content repository. The structured data below represents the complete record for this entry.

Using the roughest estimates possible as a teaching tool:

It is hard to use classical computers to simulate quantum matter because every time you add an electron, proton, photon, etc the amount of memory you need to store all the data doubles. Eg simulating 10 electrons needs about 1024 numbers to be kept in your computer's memory.

Using a quantum computer, the hardware components are also quantum so it is kind of like the available memory doubles every time you add a qubit to your processor. E.g 10 electrons can be simulated with 10 qubits of memory, which hide the 1024 "classical computer" numbers.

To simulate the entire universe you would still need a computer the size of the universe. Even worse, when you try to read the state of your memory you can only learn a tiny fraction of the data at a time, so you would need to run the simulation many times.
