Since a full theoretical treatment of atoms and molecules exposed
to intense laser pulses besides for few-electron systems is beyond
the reach of any classical computer, the idea of a quantum simulator
for attosecond physics based on ultracold atoms in optical traps
is introduced. Such a simulator should provide useful insight relevant
for many open questions related to many-electron effects in strong-field
physics. While all typical features of multiphoton as well as tunneling
and recollision physics is demonstrated to be present in the quantum
simulator, the simulator provides a large flexibility with respect
to different parameters, both for the external field and the system.
For example, the particle-particle interaction can be varied, and this
can be done independently of a variation of the trap potential that
represents the Coulomb attraction by the nuclei.
