THE PHYSICS GRADUATE PROGRAM invites everyone to the seminar:
Atomic entangling operations assisted by multiphoton states
Dr. Juan Mauricio Torres Gonzalez
IFUAP/IF – México
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.
