Chiral Quantum Sources Emit Light With Hidden Spatial Coherence

Researchers have derived the precise quantum state of light emitted from randomly oriented chiral sources, accounting for contributions from electric dipole, magnetic dipole, and electric quadrupole radiation. This work, stemming from the University of Illinois at Urbana-Champaign, details how spatial coherence within that emission can reveal previously hidden properties of the emitting molecule itself. The study describes how mutual coherence between modes of different directions and polarizations arises from both quantum and classical perspectives. This research is a companion to a concurrently submitted analysis presenting the error bounds associated…
