| contents | A novel theoretical reformulation of the conventional three-step photoemission model is presented by integrating the conceptual frameworks of constructor theory and quantum information theory. Each step of the photoemission process photon absorption, electron transport, and electron emission is formalized as a physical task (in the constructor-theoretic sense) and modeled by a quantum channel with an explicit operator-level description. This dual framework not only recovers the standard efficiency factorization n = A T D but also reveals new insights into the preservation of coherence and the interdependence of successive tasks. Furthermore, potential experimental setups and conditions under which the predicted phenomena could be observed are discussed. The motivation of this work is to pave the path for improved implementations of the current photoemission model and to contribute toward the realization of a universal constructor for quantum computation. |
