Query: Emergence of thermodynamic behavior within composite quantum systems   Entanglement within a given device provides a potential resource for quantum
information processing. Entanglement between system and environment leads to
decoherence (thus suppressing non-classical features within the system) but
also opens up a route to robust and universal control. The latter is related to
thermodynamic equilibrium, a generic behavior of bi-partite quantum systems.
Fingerprints of this equilibrium behavior (including relaxation and stability)
show up already far from the thermodynamic limit, where a complete solution of
the underlying Schroedinger dynamics of the total system is still feasible.
