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…

Modular quantum computing and quantum-like devices

- PhysicsArXiv

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.
