O PROGRAMA DE PÓS-GRADUAÇÃO EM FÍSICA convida para o seminário:

Atomic entangling operations assisted by multiphoton states*

Dr. Juan Mauricio Torres Gonzalez IFUAP/IF – México

*Evento de presença obrigatória para os alunos matriculados na disciplina seminários

Resumo:

We propose and theoretically investigate the implementation of entangling operations on two two-level atoms using cavity-QED scenarios. The atoms interact with optical cavities and their state is postselected in a noninvasive way by measuring the optical field after the interaction. We show that the resulting quantum operation can be exploited to implement quatum information protocols such as entanglement purification and a Bell state measurement. In contrast with previous purifications schemes, a fidelity larger than one half with respect to any Bell state is not a necessary condition.
