Symmetric Multiqudit States: Stars, Entanglement, Rotosensors
Chryssomalis Chryssomalakos, Louis Hanotel, Edgar Guzmán-González +3
A constellation of Majorana stars represents an arbitrary pure quantum state of dimension or a permutation-symmetric state of a system consisting of qubits. We gene…

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…

When geometric phases turn topological
Pedro Aguilar, Chryssomalis Chryssomalakos, Edgar Guzmán-González +2
Geometric phases, accumulated when a quantum system traces a cycle in quantum state space, do not depend on the parametrization of the cyclic path, but do depend on the path itself…
