DESCRIPTION:Modelling the dynamics of quantum mechanical systems\, includi
 ng molecules\, is generally an intractable problem for classical computers
 . \nHowever\, as proposed by Feynman\, the exponential computational overh
 eads associated with these simulations may be overcome by utilising a cont
 rollable quantum system that can be programmed to mimic the quantum behavi
 our of a model of interest.\nIntegrated photonics has been established as 
 a platform for quantum information processing. Recent progress in integrat
 ed photonics includes programmable circuitry\, the integration of photon s
 ources\, and single photon detection. Together with high-speed and low-los
 s photonic switches\, a versatile class of photonic quantum simulators bec
 omes a realistic prospect.\nIt is possible that the demands on error corre
 ction for specialised quantum computers\, such as quantum simulators\, cou
 ld be much lower than those for universal digital quantum computers. For p
 hotonics\, it is believed that a quantum simulator that can generate and p
 rocess more than 50 pure photons will significantly outperform a supercomp
 uter.\nI will discuss experimental demonstrations of quantum photonics as 
 a simulation platform for molecular quantum dynamics. I will cover recent 
 developments in integrated quantum photonics that will help us scale these
  simulation devices. And I will cover classical emulations techniques that
  provide important benchmarks.\n
