  We propose an efficient protocol for digital quantum simulation of quantum
chemistry problems and enhanced digital-analog quantum simulation of transport
phenomena in biomolecules with superconducting circuits. Along these lines, we
optimally digitize fermionic models of molecular structure with single-qubit
and two-qubit gates, by means of Trotter-Suzuki decomposition and Jordan-Wigner
transformation. Furthermore, we address the modelling of system-environment
interactions of biomolecules involving bosonic degrees of freedom with a
digital-analog approach. Finally, we consider gate-truncated quantum algorithms
to allow the study of environmental effects.
