Landauer erasure: Delta-Q >= k_BTlog(2) per erased bit via Shannon-McMillan-Breiman AEP

Layer 1 — Physicsin the quantum-thermodynamics subtree

Landauer erasure bound and Shannon-McMillan-Breiman AEP. Setup: a one-bit memory register in a thermal reservoir of temperature T; erasing the bit (resetting to a known state '0') reduces the register's entropy by k_B*log(2). The…
