We review concepts and methods associated with quantum discord and related topics. We
also describe their possible connections with other aspects of quantum information and …

A qubit subjected to pure dephasing due to classical Gaussian noise can be turned into a
spectrometer of this noise by utilizing its readout under properly chosen dynamical …

Quantum probing consists of suitably exploiting a simple, small, and controllable quantum
system to characterize a larger and more complex system. Here, we address the estimation …

We present a comprehensive theoretical treatment of supcode, a method for generating
dynamically corrected quantum gate operations, which are immune to random noise in the …

Controlling the non-Markovian dynamics of open quantum systems is essential in quantum
information technology since it plays a crucial role in preserving quantum memory. Albeit in …

We discuss the time evolution of entanglement, purity, and coherence of two non-interacting
maximally entangled qubits in two different classical environmental configurations: bipartite …

We investigate the preservation of quantum coherence and entanglement carried by the
three non-interacting qubits during their evolution in the presence of an external fluctuating …

We address the use of simple quantum probes for the spectral characterization of classical
noisy environments. In our scheme a qubit interacts with a classical stochastic field …

We address the time evolution of quantum correlations (QCs) such as entanglement, purity,
and coherence for a model of two non-interacting qubits initially prepared as a maximally …

We address the use of a single qubit as a quantum probe to characterize the properties of
classical noise. In particular, we focus on the characterization of classical noise arising from …
