Abstract While simple spin-boson models have been realized on quantum hardware, simulating extended electronic networks with local vibrational environments remains a fundamental challenge in the presence of non-equilibrium, long-lived electronic-vibrational (vibronic) coherence. We present a framework for the digital-analog simulation of open quantum systems governed by Hamiltonians with linear-vibronic coupling (LVC) and structured vibrational environments. Our approach exploits the intrinsic dissipation of qubits in near-term quantum hardware as a resource to emulate vibrational relaxation, combined with a model-specific error mitigation scheme to filter out noise sources incompatible with the target open system. We validate our strategy by resolving the vibronic transfer spectra of a one-dimensional donor-acceptor chain on IBM superconducting processors, reproducing non-Markovian dynamics and scaling the chain length up to 10 electronic sites, an unprecedented scale for chemical dynamics on quantum computers. Our model of vibronic electron transfer offers a portable, application-oriented benchmark for simulating long-lived entangled states on NISQ computers.

Kinetic theories at thermal equilibrium fail to accurately capture transfer rates in relevant scenarios, such as the inverted region in the Marcus theory of electron transfer1,2. This regime is for example relevant for batteries with large overpotentials, indicative of high reorganization energies and complex solvation shells3,4 that are linked to dissipative processes. A proper understanding of heat loss at the microscopic scale is crucial in the engineering of next-generation devices for energy storage and production. Nonequilibrium processes on the picosecond scale (10−12 s) are coming into focus thanks to the increasing time resolution of spectroscopic techniques5,6. Nonequilibrium quantum effects are a promising route to increase the
