This special issue of Mathematical Structures in Computer Science contains several contributions related to the modern field of Quantum Information and Quantum Computing. The first two papers deal with entanglement. The paper by R. Mosseri and P. Ribeiro presents a detailed description of the two- and three-qubit geometry in Hilbert space, dealing with the geometry of fibrations and discrete geometry. The paper by J.-G.Luque et al. is more algebraic and considers invariants of pure k-qubit… 
Quantum computation and quantum information
A survey of all the important aspects and results that have shaped the field of quantum computation and quantum information and their applications to the general theory of information, cryptography, algorithms, computational complexity and error-correction.
Modular quantum computing and quantum-like devices
A considerable amount of the power of quantum computation may be obtained by adding to a classical computer a few specialized quantum modules and such modules may be constructed out of classical systems obeying quantum-like equations where a space coordinate is the evolution parameter.
Entanglement and deterministic quantum computing with one qubit
This work presents new tools for learning about entanglement and quantum correlations in dynamical systems where the quantum states are mixed and the eigenvalue spectrum is highly degenerate and strengthens the conjecture that it may be possible to find quantum algorithms that do not generate entanglements and yet still have an exponential advantage over their classical counterparts.
Fundamentals of Quantum Information Processing
We give a brief introduction to Quantum Information Processing. We start by defining the qubit, the fundamental unity of information in a quantum system. Then, we describe how the evolution is
Geometry of Quantum Computation with Qutrits
It is shown that the optimal quantum circuits are essentially equivalent to the shortest path between two points in a certain curved geometry of SU(3n) so that three-qutrit systems are investigated in detail.
The Quantum Second Law and Quantum Information
The big progress of novel quantum information science brings about a possibility to study the role the quantum entanglement may play in different fields, e.g., quantum computation, quantum
I.Quantum bits, gates and circuits
Using the formalism of the Boolean algebra, the process of computation in quantum computers is analyzed. The description of quantum bits qubits in the Hilbert space is given, quantum logic elements,
Quantum Computation, Complexity, and Many-Body Physics
Recently developed quantum algorithms suggest that quantum computers can solve certain problems and perform certain tasks more efficiently than conventional computers. Among other reasons, this is
Intrinsic Quantum Computation
Quantum Information and Teleportation
Quantum mechanics, despite its lack of intuitiveness, has been very successful in describing and predicting physical systems. The field of quantum computation and information seeks to use quantum
