Canonical designation

$\boxed{\rho_0\overset{\mathcal E_t}{\longmapsto}\rho_t,\qquad S(\rho_t)=-\operatorname{Tr}(\rho_t\log\rho_t)}$

A monotone-compression claim is recorded only on intervals and under channels for which

$S(\rho_t)\downarrow

is proved or numerically observed.

Origin family

Identity boundary

Entropy reduction is not universal under arbitrary quantum channels. Citizenship therefore binds the trajectory to its explicit Hamiltonian, collapse operators, initial state and time domain.

Quantum credential

Qubit count; GHZ or other initial state; damping/dephasing rates; master equation; trace and positivity residuals; entropy series; fidelity series; solver version; run hash.
