Abstract

In the present paper, quantum coherence of fermionic Gaussian states is investigated from the point of quantum resource theory. Some characterizations of

m

-mode (

m \geq 1

) incoherent fermionic Gaussian states and incoherent fermionic Gaussian channels are obtained, two quantification measures of fermionic Gaussian quantum coherence based on respectively the relative entropy and the Hellinger distance are proposed, and some formulas to calculate the value of these measures are established. It is shown that the

m

-mode fermionic Gaussian coherence is a quantum resource.

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
