title: Coherence and decoherence in biological systems: principles of noise-assisted transport and the origin of long-lived coherences.
abstract: The quantum dynamics of transport networks in the presence of noisy environments has recently received renewed attention with the discovery of long-lived coherences in different photosynthetic complexes. This experimental evidence has raised two fundamental questions: firstly, what are the mechanisms supporting long-lived coherences; and, secondly, how can we assess the possible functional role that the interplay of noise and quantum coherence might play in the seemingly optimal operation of biological systems under natural conditions? Here, we review recent results, illuminate them by means of two paradigmatic systems (the Fenna-Matthew-Olson complex and the light-harvesting complex LHII) and present new progress on both questions.
