The+-sign in the figure represents the smallest inseparable unit of positive and negative electromagnetic information-quantum bit.

(john wheeler, a famous physicist, once famously said: Everything comes from bit by bit.

After the prosperity of quantum information research, this concept has been sublimated to everything from quantum bits.

Note: One point is one point.
