DESCRIPTION:Noisy intermediate-scale quantum devices provide a promising p
 latform for exploring non-equilibrium quantum dynamics. Building on this o
 pportunity\, we theoretically explore open-system evolution implemented on
  digital quantum computers via repeated interactions between a quantum sys
 tem and auxiliary qubits. After each interaction\, the auxiliary qubits ar
 e measured\, and the resulting sequence of measurement outcomes defines a 
 quantum trajectory. By interpreting trajectories as microstates of an effe
 ctive ensemble\, we construct dynamical analogues of equilibrium concepts 
 such as free energy and entropy. This framework allows us to bias quantum 
 trajectories and tailor their properties—e.g.\, temporal correlations—
 in a controlled manner. Applying our approach to a many-body model inspire
 d by dual-species Rydberg-atom experiments\, we uncover rich heterogeneous
  behaviour and glassy dynamics that remain hidden in the average-state evo
 lution. By leveraging the aforementioned thermodynamic-like functionals\, 
 we identify these features as signatures of a first-order dynamical phase 
 transition.
