- Abstract: 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).

The No-Free-Lunch (NFL) theorem quantifies problem- and data-independent generalization errors regardless of the optimization process.
We categorize a diverse array of quantum learning algorithms into three learning protocols designed for learning quantum dynamics under a specified observable.
Our derived NFL theorems demonstrate quadratic reductions in sample complexity across CLC-LPs, ReQu-LPs, and Qu-LPs.
We attribute this performance discrepancy to the unique capacity of quantum-related learning protocols to indirectly utilize information concerning the global phases of non-orthogonal quantum states.

Next, we prove how the generalization error bound of QGANs depends on the employed Ansatz, the number of qudits, and input states.
