Quantifying quantum coherence in a metal-silicate framework

Abstract

The study of quantum coherence in condensed matter systems is a broad avenue to be explored toward the enhancement of its quantum properties by means of material engineering. In this regard, the present work reports a study of the influence of temperature, pressure and magnetic fields on the quantum coherence of a Cu(II) metal-silicate framework. We calculate the l1 trace norm quantum coherence as a function of the magnetic susceptibility of the compound, which allows us to evaluate the effects of these external parameters on the degree of coherence of the material. Our results show that the quantum coherence of a low-dimensional molecular magnetic system can be handled by the management of the external conditions, offering new prospects for quantum coherence measurements through magnetometric experiments.
