Abstract
present new challenges for modelling such systems, which could be amenable
to quantum simulation methods. Here, by exploiting a natural mapping
between vibrations in molecules and photons in waveguides, we demonstrate
a reprogrammable photonic chip as a versatile simulation platform for a range
of quantum dynamic behaviour in different molecules. We begin by
simulating the time evolution of vibrational excitations in the harmonic
approximation for several four-atom molecules, including H CS, SO ,
HNCO, HFHF, N and P . We then simulate coherent and dephased energy
transport in the simplest model of the peptide bond in proteins—Nmethylacetamide—
and simulate thermal relaxation and the effect of
anharmonicities in H O. Finally, we use multi-photon statistics with a
feedback control algorithm to iteratively identify quantum states that increase
a particular dissociation pathway of NH . These methods point to powerful
new simulation tools for molecular quantum dynamics and the field of
femtochemistry.
