Abstract

Quantum coherence, which exhibits the fundamental signature of superposition in quantum mechanics, has been exploited in many fields of quantum physics, such as biological systems [1–3], transport theory [4, 5], thermodynamics [6–12], nanoscale physics [13] and other scientific work associated with quantum theory [14–21]. Recently, rigorous and unambiguous framework for quantifying quantum coherence has also been put forward, which has enhanced the exploitation of its operational significance in the context of quantum resource theory [22–24].
