Doesn't this also assume a computer similar to our own? How would this principle apply to a biological computer for example?

- lann 9y ago> Doesn't this also assume a computer similar to our own? No. It is about abstract computation, which is based on (our best understanding of) theoretical physics.
- Armisael16 9y agoThe Landauer limit applies to all non-thermodynamically reversible changes of state in a system. I don't know how your biological computer works, so I can't say 100% that it applies - but it probably does.
- SAI_Peregrinus 9y agoThe Landauer principle applies to any computer made of matter utilizing energy (in a non-thermodynamically reversible fashion). So it applies just fine to biological computers, quantum computers, and even mechanical computers! It's a result in quantum information theory, and doesn't have anything to do with the overall type of computer used. It just determines how much energy it takes to change the state of a quantum (particle), at a minimum. Things like changing the polarization of a photon or the spin of an electron.
