The coherent superposition of states, in combination with the quantization of observables,
represents one of the most fundamental features that mark the departure of quantum …

Open quantum systems (OQSs) cannot always be described with the Markov approximation,
which requires a large separation of system and environment time scales. An overview is …

Photonic quantum technologies represent a promising platform for several applications,
ranging from long-distance communications to the simulation of complex phenomena …

Photosynthetic antenna complexes capture and concentrate solar radiation by transferring
the excitation to the reaction center that stores energy from the photon in chemical bonds …

Quantum control is concerned with active manipulation of physical and chemical processes
on the atomic and molecular scale. This work presents a perspective of progress in the field …

Recent years have seen tremendous progress in the theoretical understanding of quantum
systems driven dissipatively by coupling to different baths at their edges. This was possible …

Quantum biology is an emerging field of research that concerns itself with the experimental
and theoretical exploration of non-trivial quantum phenomena in biological systems. In this …

We develop an extension of the variational quantum eigensolver (VQE) algorithm—
multistate contracted VQE (MC-VQE)—that allows for the efficient computation of the …

Recent observations of oscillatory features in the optical response of photosynthetic
complexes have revealed evidence for surprisingly long-lasting electronic coherences …

The study of open quantum systems often relies on approximate master equations derived
under the assumptions of weak coupling to the environment. However when the system is …
