Protecting Quantum States via the Super-Zeno Effect and Anticoherence

C. Chryssomalakos, A. G. Flores-Delgado, E. Guzmán-González +1

We consider a spin system coupled to a noisy environment via an interaction Hamiltonian which is a polynomial of degree in the spin operators (-magnetic Hamiltonia…

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…

Toponomic Quantum Computation

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

Holonomic quantum computation makes use of non-abelian geometric phases, associated to the evolution of a subspace of quantum states, to encode logical gates. We identify a special…

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…
