DESCRIPTION:A promising application of fault tolerant quantum computers is
  the simulation of quantum systems. In realistic settings\, quantum syste
 ms interact with their surrounding environments\, implying that effects o
 f environments must be accounted for to achieve faithful simulation. It h
 as\, since the early days of quantum computing\, been understood that the
  effects of an environment on a quantum system can be emulated by couplin
 g to an ancillary system of comparable size. In this talk\, we present a 
 resource-efficient method for simulating the effects of any Gaussian bath
  independent of the system size. The method uses a stream or [i]train[/i]
  of ancillary qubits to emulate the interaction between the environment a
 nd the system. Given any non-zero target accuracy and any Gaussian enviro
 nment\, we provide rigorous resource estimates. Notably\, the method can 
 be used to simulate strong system-environment interactions and non-Markov
 ian effects.The talk is based on joint work with Hans Michael Christensen
  and Frederik Nathan.
