Speed excess and total acceleration: a kinematical approach to entanglement

C. Chryssomalakos, A. G. Flores-Delgado, E. Guzmán-González +2

We show that the concept of total variance of a spin state, defined as the average of the variances of spin projection measurements along three orthogonal axes, also gives the rota…

Curves in quantum state space, geometric phases, and the brachistophase

C. Chryssomalakos, A. G. Flores-Delgado, E. Guzmán-González +2

Given a curve in quantum spin state space, we inquire what is the relation between its geometry and the geometric phase accumulated along it. Motivated by Mukunda and Simon's resul…

Maximum entanglement of mixed symmetric states under unitary transformations

E. Serrano-Ensástiga, J. Martin

We study the maximum entanglement that can be produced by a global unitary transformation for systems of two and three qubits constrained to the fully symmetric states. This restri…

Majorana representation for mixed states

E. Serrano-Ensástiga, D. Braun

We generalize the Majorana stellar representation of spin- pure states to mixed states, and in general to any hermitian operator, defining a bijective correspondence between thr…

Stellar Representation of Grassmannians

C. Chryssomalakos, E. Guzmán-González, L. Hanotel +1

Pure quantum spin- states can be represented by points on the sphere, as shown by Majorana in 1932 --- the description has proven particularly useful in the study of rotati…
