One of the greatest challenges in the fields of quantum information processing and quantum
technologies is the detailed coherent control over each and every constituent of quantum …

Entanglement is a fundamental concept in quantum mechanics. In this review, we study
various aspects of coherence and entanglement, illustrated by several examples. We relate …

We study the statistical distribution of the ergotropy and of the efficiency of a single-qubit
battery ad of a single-qubit Otto engine, respectively fueled by random collisions. The single …

The channel induced by a complex system interacting strongly with a qubit is calculated
exactly under the assumption of randomness of its eigenvectors. The resulting channel is …

We investigate the generation of entanglement between two noninteracting qubits coupled
to a common reservoir. An experimental setup was conceived to encode one qubit on the …

We study competition between the dissipative and coherent effects in the entanglement
dynamics of two qubits. The coherent interactions are needed for designing logic gate …

A major challenge in exploiting the principles of quantum information is the influence of
noise which tends to work against the quantum features of a system. The traditional quantum …

Knowledge of the relationships among different features of quantumness, like entanglement
and state purity, is important from both fundamental and practical viewpoints. Yet, this issue …

We analyze the dynamics of a system qudit of dimension μ sequentially interacting with the ν-
dimensional qudits of a chain playing the role of an environment. Each pairwise collision …

The eigenstate thermalisation hypothesis (ETH) is a statistical characterisation of eigen-
energies, eigenstates and matrix elements of local operators in thermalising quantum …
