Near-unity energy transfer efficiency has been widely observed in natural photosynthetic
complexes. This phenomenon has attracted broad interest from different fields, such as …

Several techniques of generating random quantum channels, which act on the set of d-
dimensional quantum states, are investigated. We present three approaches to the problem …

Understanding whether dissipation in an open quantum system is truly quantum is a
question of both fundamental and practical interest. We consider n qubits subject to …

We provide a detailed discussion about the unitary and reduced evolution induced by family
of Hamiltonian models describing a multilevel system, with a ground state and a possibly …

It is often assumed that decoherence arises as a result of the entangling interaction between
a quantum system and its environment, as a consequence of which the environment …

The contact process is a paradigmatic classical stochastic system displaying critical
behavior even in one dimension. It features a nonequilibrium phase transition into an …

Quantum coherence, the physical property underlying fundamental phenomena such as
multi-particle interference and entanglement, has emerged as a valuable resource upon …

One of the central problems in quantum theory is to characterize, detect, and quantify
quantumness in terms of classical strategies. Dephasing processes, caused by non …

We show that the effect of a Gaussian bosonic environment linearly coupled to a quantum
system can be simulated by a stochastic Lindblad master equation characterized by a set of …

We suggest a quantum simulator that allows to study the role of memory effects in the
dynamics of open quantum systems. A particular feature of our simulator is the ability to …
