The electronic excited states of molecular aggregates and their photophysical signatures
have long fascinated spectroscopists and theoreticians alike since the advent of Frenkel …

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 …

Solar fuel production often starts with the energy from light being absorbed by an assembly
of molecules; this electronic excitation is subsequently transferred to a suitable acceptor. For …

Coherence phenomena arise from interference, or the addition, of wave-like amplitudes with
fixed phase differences. Although coherence has been shown to yield transformative ways …

Quantum simulators are controllable quantum systems that can be used to mimic other
quantum systems. They have the potential to enable the tackling of problems that are …

The key to explaining and controlling a range of quantum phenomena is to study how
information propagates around many-body systems. Quantum dynamics can be described …

Recent evidence suggests that a variety of organisms may harness some of the unique
features of quantum mechanics to gain a biological advantage. These features go beyond …

Studies of the dynamics of open quantum systems are limited by the large Hilbert space of
typical environments, which is too large to be treated exactly. In some cases, approximate …
