Logica e Informatica Teorica Quantum Information: Extending the Bloch sphere model for two o more qubits, and relation with Group Theory Fernando Cuartero 14-01-2022 - 15:00 Largo San Leonardo Murialdo,1 - Pal.C - Aula 311
The Bloch Sphere Model can be used to easily visualize the effect of applying quantum gates on a qubit, or the temporal evolution of the state of a two-level system described by a Hamiltonian. It is clear that some geometric pictures give us great help in understanding some quantum information or quantum algorithms problems. Thus, the representation of a unit vector by means of the Bloch Sphere is powerful for a single qubit. Nevertheless, there is no commonly accepted representation for a quantum system for two o more qubits so far, even when we can find some papers reported in the literature on the subject. And this is the objective of the first part of the talk. |
