I believe the double well model—although it sounds somewhat specific at a glance—is actually a fully universal conceptual category over all relevant computational options for representing a bit.
You can represent a bit with dominoes, in which case the two bistable states are up/down, you can represent it with few electron quantum dots in one of two orbital configs, or larger scale wire charge changes, or perhaps fluid pressure waves, or ..
The exact form doesn’t matter, as a bit always requires a binary classification between two partitions of device microstates, which leads to success probability being some exponential function of switching energy over noise energy. It’s equivalent to a binary classification task for maxwell’s demon.
