- Abstract: The most important problem of spectroscopic chiral analysis is the inherently
weak chiral signals are easily overwhelmed by the environment noises. Enormous
efforts had been spent to overcome this problem by enhancing the symmetry break
in the light-molecule interactions or reducing the environment noises. Here, we
propose an alternative way to solve this problem by using frequency-entangled
photons as probe signals and detecting them in coincidence, i.e., using quantum
chiral spectroscopy. For this purpose, we develop the theory of
entanglement-assisted quantum chiral spectroscopy. Our results show that the
signals of left- and right-handed molecules in the quantum spectrum are always
distinguishable by suitably configuring the entangled probe photons. In
construct, the classical spectrum of the two enantiomers become
indistinguishable when the symmetry break in the interactions is overwhelmed by
the environment noises. This offers our quantum chiral spectroscopy a great
advantage over all classical chiral spectroscopy. Our work opens up an exciting
area that exploring profound advantages of quantum spectroscopy in chiral
analysis.
