A scalable architecture for quantum computing requires logical units supporting quantum-error correction. In this respect, magnetic molecules are particularly promising, since they allow one to define logical qubits with embedded quantum-error correc

We numerically investigate the properties of the quasihole excitations above the bosonic fractional Chern insulator state at filling ν=1/2, in the specific case of the Harper-Hofstadter Hamiltonian with hard-core interactions. For this purpose, we e

The recent discovery of single-ion magnets with magnetic hysteresis above liquid-nitrogen temperatures placed these compounds among the best candidates to realize high-density storage devices. Starting from a prototypical dysprosocenium molecule, sho
