Quantum Complexity and New Directions in Nuclear Physics and High-Energy Physics Phenomenology
Caroline E. P. Robin, Martin J. Savage
Advances in quantum information science (QIS) are providing transformative insights into the complexity of quantum many-body systems, potentially defining new frontiers in nuclear…
Neural Quantum States in Non-Stabilizer Regimes: Benchmarks with Atomic Nuclei
James W. T. Keeble, Alessandro Lovato, Caroline E. P. Robin
As neural networks are known to efficiently represent classes of tensor-network states as well as volume-law-entangled states, identifying which properties determine the representa…
Stabilizer-Accelerated Quantum Many-Body Ground-State Estimation
Caroline E. P. Robin
We investigate how the stabilizer formalism, in particular highly-entangled stabilizer states, can be used to describe the emergence of many-body shape collectivity from individual…
Anti-Flatness and Non-Local Non-stabilizerness in Two-Particle Scattering Processes
C. E. P. Robin, M. J. Savage
Non-local non-stabilizerness and anti-flatness provide a measure of the quantum complexity in the wavefunction of a physical system. Supported by entanglement, they cannot be remov…
Quantum Complexity Fluctuations from Nuclear and Hypernuclear Forces
Caroline E. P. Robin, Martin J. Savage
Toward an improved understanding of the role of quantum information in nuclei and exotic matter, we examine the quantum magic (non-stabilizerness) in low-energy strong interaction…
Quantum Magic and Multi-Partite Entanglement in the Structure of Nuclei
Florian Brökemeier, S. Momme Hengstenberg, James W. T. Keeble +3
Motivated by the Gottesman-Knill theorem, we present a detailed study of the quantum complexity of -shell and -shell nuclei. Valence-space nuclear shell-model wavefunctions…
