Landauer bound Q_min = k_B*T*log(2); at T = 300 K, Q_min ~ 2.87e-21 J/bit

Landauer bound exact value. From framework F7 (SMB-AEP reduction to single-bit), the minimum heat dissipated per logical bit erasure is Q_Landauer = k_B*T*log(2). Sympy canonical pin (positive symbols k_B, T): Q = 'T*k_B*log(2)'. At room…
