In our study, we investigate the phenomenon of information loss, as measured by the Kullback–Leibler divergence, in a many-fermion system, such as the Lipkin model. Information loss is introduced as the number N of particles increases, particularly

Quantum simulation of molecules without fermionic encoding of the wave function

Autor: David A Mazziotti, Scott E Smart, Alexander R Mazziotti

Publikováno v: New Journal of Physics, Vol 23, Iss 11, p 113037 (2021)

Molecular simulations generally require fermionic encoding in which fermion statistics are encoded into the qubit representation of the wave function. Recent calculations suggest that fermionic encoding of the wave function can be bypassed, leading t

The present contribution summarizes the content and slightly updates the discussion of a recently proposed theoretical analysis of the halo phenomenon in many-fermion systems. We focus here on applications to potential neutron halos in mid-mass nucle
