In this Chapter we review the core ingredients of a class of mixed quantum-classical methods that can naturally account for quantum coherence effects. In general, quantum-classical schemes partition degrees of freedom between a quantum subsystem and an environment. The various approaches are based on different approximations to the full quantum dynamics, in particular in the way they treat the environment. Here we compare and contrast two such methods: the Quantum Classical Liouville (QCL) approach, and the Iterative Linearized Density Matrix (ILDM) propagation scheme. These methods are based on evolving ensembles of surface-hopping trajectories in which the ensemble members carry weights and phases and their contributions to time-dependent quantities must be added coherently to approximate interference effects. The side by side comparison we offer highlights similarities and differences between the two approaches and serves as a starting point to explore more fundamental connections between such methods. The methods are applied to compute the evolution of the density matrix of a challenging condensed phase model system in which coherent dynamics plays a critical role: the asymmetric spin-boson. Various implementation questions are addressed.
