- Abstract: We present a scheme to realize precise discrimination of chiral molecules in
a cavity. Assisted by additional laser pulses, cavity fields can evolve to
different coherence states with contrary-sign displacements according to the
handedness of molecules. Consequently, the handedness of molecules can be read
out with homodyne measurement on the cavity, and the successful probability is
nearly unity without very strong cavity fields. Numerical results show that the
scheme is insensitive to errors, noise and decoherence. Therefore, the scheme
may provide helpful perspectives for accurate discrimination of chiral
molecules.

Since some novel molecules may not meet the basic requirements of real-world drugs, MOOD performs conditional generation by utilizing the gradients from a property predictor.
We experimentally validate that MOOD is able to explore the chemical space beyond the training distribution, generating molecules that outscore ones found with existing methods, and even the top 0.01% of the original training pool.
