Harvesting Quantum Resources
Quantum resource theories play a prominent role in quantum mechanics, providing a rigorous framework for quantifying and utilizing nonclassical features such as entanglement, coherence, magic and nonlocality. Harvesting protocol is a powerful tool for extracting quantum resources from a quantum field through interaction with a system of detectors. These protocols lie at the intersection of quantum information theory, quantum field theory, and the foundations of quantum mechanics, offering a unique perspective on fundamental quantum phenomena. Notably, harvesting enables the exploration of Bell inequality violations in field-theoretic settings, shedding light on the intricate interplay between locality, causality, and correlations in relativistic quantum systems.
Quantum simulation of fundamental physics
Within the current technological landscape, quantum computers present a unique opportunity to simulate new theories, offering theoretical insights and guiding future experimental developments. Non-stabilizer resources are expected to play a crucial role in these simulations, as they quantify the complexity of quantum states.
An example of this is the role of non-stabilizerness in quantum gravity simulations. By computing the stabilizer entropy of the fundamental states of a theory, we aim to establish lower bounds on the computational resources required for their experimental realization. Furthermore, we can analyze how gauge invariance constraints inherently demand non-stabilizer resources, contributing to the computational complexity of simulating quantum geometric states.
The results of this study will provide valuable insights into the simulability of quantum gravity states and the feasibility of experimental tests of quantum spacetime structures. Moreover, the same techniques can be implemented in the development of quantum computing strategies for exploring fundamental questions in particle physics and fundamentl interactions.
