- Authors: A. C. S. Costa, R. M. Angelo
- Abstract summary: Resource theories identify resourceful states and channels that are potentially useful for the accomplishment of tasks that would be otherwise unreachable.
We develop a unifying approach that proves able to encompass several nonclassical aspects, including the newly developed concepts of quantum irreality and realism-based nonlocality.

- Abstract: Resource theories play an important role in quantum information theory, as
they identify resourceful states and channels that are potentially useful for
the accomplishment of tasks that would be otherwise unreachable. The elementary
structure of such theories, which is based on the definition of free states and
free operations, successfully accommodates different nonclassical aspects, such
as quantum coherence and entanglement, but it is still not clear whether and
how far such formal framework can be extended. In this work, by taking
information as the most primitive quantum resource and defining
resource-destroying operations, we develop a unifying approach that proves able
to encompass several nonclassical aspects, including the newly developed
concepts of quantum irreality and realism-based nonlocality.

- Separable Power of Classical and Quantum Learning Protocols Through the Lens of No-Free-Lunch Theorem [70.42372213666553]
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.

This characteristic ensures the impossibility of interpreting the results of quantum measurements as revealing properties that are independent of the set of measurements being made.
We will use the so called cost and yield monotones, extending the results of reference Quantum 4, 280 ( 2020) to general contextuality scenarios.
