This study derives the one-photon state of the electromagnetic field emitted by a randomly oriented chiral quantum source, incorporating contributions from electric dipole, magnetic dipole, and electric quadrupole radiation. By leveraging the spatial coherence of the emitted light, the authors demonstrate a method to extract hidden information about the emitter's properties. This foundational work sets the stage for further exploration of error bounds related to determining the handedness of chiral emitters in a companion paper.
Spatial coherence can unveil hidden properties of chiral quantum sources, revealing insights previously obscured in random orientations.
We derive the form of the one-photon state of the electromagnetic field resulting from spontaneous optical emission of a randomly oriented chiral quantum source, including electric dipole, magnetic dipole, and electric quadrupole contributions to the radiation. We describe how spatial coherence in the emission can be exploited to reveal hidden information about the emitter. This work serves as a prelude and companion piece to our concurrently submitted work \cite{Backlund2026Letter} in which we present the classical and quantum error bounds associated with assigning the handedness of such an emitter.
