| contents | We present our program for the development of quantum informational concepts in relativistic systems in terms of the unequal-time correlation functions of quantum fields. We employ two formalisms that provide the basis for further developments. (i) The Quantum Temporal Probabilities (QTP) Method for quantum field measurements and (ii) the Closed- Time-Path (CTP) formalism for causal time evolutions. We present the main ideas of QTP and show how it relates to the CTP formalism, allowing one to express concepts of measurement theory in terms of path-integrals. We also present many links of our program to non-equilibrium quantum field theories. Details can be found in a recent paper by the authors (arxiv:2208.03696). |
