The Quantum Entanglement And Anti-Bunching Effect In T-C Model

T-C model, as a very effective model, has been applied in quantum computing,quantum cryptography distribution, quantum error correction, quantum coding, quantumteleportation, optical communication, weak signal detection and human visual system.The interaction of light and particles, particles and particles and their special propertieshave been effectively researched by using T-C model as the research object. Thisprovides a strong basis for quantum information, quantum optics theory research andrealizing quantum computation. Quantum entanglement and anti-bunching effect play avery important role in the study of quantum physics basic problems during the highspeed development period of quantum computation. The measure of quantumentanglement is a very important problem in quantum entanglement research. Untilnow, people have been able to give good measure for the ideal state of two bodyentanglement, and have put forward a variety of entanglement measurement methodwith the deepening of understanding. But in the experimental study, a lot of externalfactors, such as: dissipation, the spontaneous radiation of particles and the frequencyfluctuation, can influence the results. So considering these factors is especiallyimportant to our research in theory study. Based on the above, the further research forthe nonideal state of entanglement is still worth doing. Therefore, in this article, westudy the influence of cavity dissipation on entanglement and cavity frequency whichmakes a small oscillation with time on anti-bunching effect in T-C model.This paper introduces the concurrence measurement method, which is one ofthe most commonly used entanglement measurement method, and the basic theory ofanti-bunching effect. Using the T-C model as the research object, this paper probes intothe influence of initial state and cavity field dissipative for the concurrence and theeffect of fluctuation of optical field on anti-bunching. The results imply that themaximum entanglement can be prepared by controlling the interacting time. Because ofthe atomic two-photon transition, the two-photon T-C model needs less time than thesingle photon T-C model in the preparation of maximally entangled state. Due to atomicspontaneous emission and cavity field loss, the correlation information of two atomsdecreased gradually over time and until the last correlation information is zero. Lightfield frequency over time, a slight oscillation will destroy the classic nature of thephoton. As the oscillation amplitude increases, the non-classical nature of the photon ismore obvious. When the oscillation frequency increases, the curve of second-ordercoherent of photons periodically sinks. This effect seems more clearly when theamplitude of vibration increases. And increases along with the photon frequency, thepresented frequency is also getting higher and higher.
