    Classical and quantum algorithms for many-body problems by Ayral, Thomas

    Published 2025-01-01
    “…After describing a method based on natural orbitals for shortening, and thus making more reliable, quantum circuits to prepare fermionic states, we present a method based on slave spins for using a platform of Rydberg atoms to simulate lattice models of fermions. Finally, we show how these same Rydberg platforms can be used to solve combinatorial problems, and how decoherence influences the quality of the results obtained. …”
