Abstract

It is well known that the set of m-body reduced density matrices of N-body states (possibly satisfying a symmetry constraint) is convex. This also holds for vectors of m-body quantum marginals.

Abstract

I will introduce a family of quantum devices, which can be described by state-swapping operations. They include quantum state transfer, quantum state amplifier, entanglement creator... We propose a unified method to study them. The method may also lead to innovative designs of quantum devices or setups.

In this lecture I will introduce some of the questions that we may wish to answer in quantum biology. Then I will focus on excitation energy transport in photosynthetic complexes. I will explain the crucial role of the interplay of quantum coherent evolution with environmental noise and provide an explanation of the origin and nature of the long-lived coherences that have been observed in the recent 2-D spectroscopy experiments of the FMO complex.
