Quantum mechanical entanglement of several qubits is not only the essential ingredient for quantum information, but also relevant for biological systems. Solid evidence exists that the photosynthetic complexes in bacteria and plants operate using entanglement between their light harvesting molecules, which can consequently be described as qubits. To understand this, it is crucial to include the decohering influence of the proteins surrounding these molecules. Modern femtosecond laser experiments can probe the qubit dynamics on a femtosecond time scale. Their interpretation requires a theory that properly explains quantum mechanical effects in the protein environment and the typical time scale on which it evolves. We develop such theory to go beyond the commonly used approximation of an ultrafast environment and study the effects on qubit entanglement.
