Previous issue date: 2011-03-04 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / Taking advantage of the Faraday rotations that occur in a photonic cristal placed
in an optical cavity with low quality factor, we proposed two schemes to obtain
the swapping of entanglement of atomic states, useful in quantum communication
and quantum computation. They employ three-level atoms in a -configuration, a
linearly polarized photon source, a single detector, and a quarter wave plate. Three
(four) cavities are used in the first (second) scheme. An additional scheme was also
proposed to obtain controlled teleportation of superposition states, partial controlled
teleportation of entangled states and controlled teleportation of entanglement.
In all schemes we have included the imperfections that affect the system, such as
transmission and coupling of photons in optical components, the fraction of photons
with a desired polarization, the quantum efficiency of single photon detection, the
effective solid angle where the photon are collected, and the rate of emitted photons
by the source. Under these realistic conditions we estimate the success probability
of each proccess, including the time spent for its realization. / Aproveitando as rotações de Faraday que ocorrem em um cristal fotônico colocado
em uma cavidade óptica com baixo fator de qualidade, propusemos dois esquemas
para obter a troca de emaranhamento de estados atômicos, útil em comunicação
quântica e computação quântica. Eles empregam átomos de três níveis em uma
configuração, uma fonte de fótons com polarização linear, um único detector,
e uma placa de quarto de onda. Três (quatro) cavidades são usadas no primeiro
(segundo) esquema. Um método adicional foi também proposto para obter teletransporte
controlado de estados de superposição, teletransporte parcial controlado
de estados emaranhados e teletransporte controlado de estados emaranhados. Em
todos os esquemas incluímos as imperfeições que afetam o sistema, tais como a
transmissão e acoplamento de fótons em componentes ópticos, a fração de fótons
com uma polarização desejada, a eficiência quântica da detecção de um único fóton,
o ângulo sólido efetivo em que o fótons são coletados e a taxa de fótons emitidos
pela fonte. Sob estas condições realistas, estimamos a probabilidade de sucesso de
cada processo, incluindo o tempo gasto para sua realização.
