Recently, there has been much interest in a new kind of “unspeakable” quantum information
that stands to regular quantum information in the same way that a direction in space or a …

Any physical process can be represented as a quantum channel mapping an initial state to a
final state. Hence it can be characterized from the point of view of communication theory, ie …

Holography is a cornerstone characterization and imaging technique that can be applied to
the full electromagnetic spectrum, from X-rays to radio waves or even particles such as …

We present a general model for quantum channels with memory and show that it is
sufficiently general to encompass all causal automata: any quantum process in which …

In this volume, six review articles which cover a broad range of topics of current interest in
modern optics are included. The first article by S. Saltiel, AA Sukhorukov and YS Kivshar …

We provide the optimal measurement strategy for a class of noisy channels that reduce to
the identity channel for a specific value of a parameter (spreading channels). We provide an …

Quantifying and verifying the control level in preparing a quantum state are central
challenges in building quantum devices. The quantum state is characterized from …

We formally extend the notion of Markov order to open quantum processes by accounting for
the instruments used to probe the system of interest at different times. Our description …

The long-time maintenance of quantum coherence is crucial for its practical applications. We
explore decoherence process of a multiqubit system passing through a correlated channel …

In this paper, we develop, step by step, the framework for universal dynamical control of two-
level systems (TLS) or qubits experiencing amplitude or phase noise (AN or PN) due to …
