IBM Scientists Measure the Heat Emitted From Erasing a Single Bit

To store information, you need the ability to set something into at least two possible states, one of which can be the intrinsic state. No matter what you use for storage, you'll always need energy to reach the non-intrinsic state(s), since the intrinsic state is, essentially by definition, the state achieved with no external energy applied.

If you must add energy to enter a non-intrinsic state, it makes perfect sense that the energy would need to be dissipated to return to the intrinsic state (which equates
