Second, an entangled joint state with 0 : now [ ] need not vanish, and, more importantly, it need not be assignable to “the system’s energy” or “the bath’s energy” separately at all. It is a property of the correlations in the joint state itself, a genuine interaction and correlation energy that a bipartite split has no vocabulary to divide further. Quantum thermodynamics has had to confront exactly this ambiguity in defining work, heat, and internal energy for open systems with non-negligible system-bath correlations, and the resolution adopted there is the one adopted here: report the total defect exactly, and do not pretend to resolve an assignment the…

The honest limitation is not in any of those checks; it is in what the construction was never built to promise. is a number attached to one named channel and one named coarse Hamiltonian, not an observer-independent fact about “the” missing energy. A different, equally legitimate choice of — a different split of which few collective degrees of freedom count as “the system,” or a different unitary dilation of the same open dynamics, since Stinespring’s theorem guarantees a dilation exists but not that it is unique [ 9 ] — will generally return a different nonzero reading for the identical experiment, and nothing in the operator itself adjudicates which choice is…
