Copy parameters
Copier starts out in a known state
- Otherwise we have to apply energy to erase it
- System has 2 states before copying, and 2 after
2 adjustable parameters in the copier
- We adjust the barrier height
- The model adjusts the copier trough depths
We must ensure that the dot occupies a unique minimum energy at all times
- Work done moving barrier must be negligible
- Kinetic energy of dot must be negligible
- Otherwise process is not reversible
