Close enough for a popsci article!
- gus_massa 8y agoI agree. There are a million of differences, but the main idea is the same. You go from an very ordered state to an state that looks unordered, but it's actually very specific state (with a weird order that is not evident). Then in one case you reverse the mechanical part and the fluid movement is reversed and you get back to the initial state. (Well, almost the initial state because there is some diffusion and other non reversible effects.) In the other case, you apply a transformation that reverse the "speed" of the particles (even if they are entangled, without destroying the entanglement, here a few technical details that is better to avoid), and you get back to the initial state. (Well, almost because if you are unlucky soothing can affect unexpectedly the system and you loose the control and you don't return to the initial state. Errors like this are more probable when you use more qbits.)
