Is there a fundamental physical limitation to the amount of space needed to contain a single bit?
In: 1
Follow up question to this: Often I see the answer to this question as how many particles could be fit into a space. The information density is the number of particles, (or their absence), with specific areas corresponding to specific bits – the presence of a particle being a 1 where the absence is 0.
Isn’t it possible that more information could be stored in a single particle when you take into consideration its orientation and exact placement? What about quantifying its direction of travel and using that as information? I propose that a single particle could have a very large (infinite?) amount of data – it’s existence or non existence; X, Y, Z locations in a given space; X’, Y’,Z’ rotation; linear momentum; and rotational momentum.
Teach me how I am wrong.
