Description
In this talk, I will present a unified quantum framework for axion dark matter detection. Drawing on a quantum-optics-inspired formalism, we describe realistic axion dark matter detection schemes through a density matrix and a corresponding quasi-probability distribution. We show that the intrinsically quantum nature of the dark matter field will remain unobservable with current or foreseeable technology due to mode averaging and extremely low conversion efficiency. Our results exemplify why the classical-field treatment of wave dark matter remains both accurate and sufficient for present searches, and also provides a general method to compute effects arising from dark matter states.
