Therefore, it is desirable to study a non-Markovian effects of the decoherence and disentanglement in any viable realization of qubits.

Thus in this thesis, we will made a detailed introduction of our method--perturbation based on unitary transformation, and apply it to several models to investigate the Non-Markovian decoherence and disentanglement dynamics of dissipation two-state system.

So the effect of the environment to the quantum system becomes a center topic, the key of which is to eliminate or suppress the dissipation effect on the quantum system imposed by its surrounding environment, such as decoherence and disentanglement.

新興的量子信息科學(xué)美女国产福利网站，包括量子調(diào)控、量子計(jì)算與量子通信領(lǐng)域人人漂人人操，無不有賴于小尺寸器件之間的量子相干性国内机关自拍视频在线观看，無不希望量子器件能夠不受外界環(huán)境的影響或減小環(huán)境的影響。

Among these methods, it is surprising that few if any fundamental treatments of decoherence exist that include the dynamics of disentanglement with better than the Markovian approximation or phenomenological tradition.

For example, Milburn gave a simply model of intrinsic decoherence, and made a simply modification to the standard quantum mechanics.

其中精品国产黄，Milburn提出了一個(gè)簡(jiǎn)單的內(nèi)稟退相干模型一级A片免观看，給出了對(duì)標(biāo)準(zhǔn)量子力學(xué)的簡(jiǎn)單修正。

Numerical calculations are performed on the decoherence rate as a function of the polar angle, the Coulomb binding parameter, the coupling strength, the confinement length of quantum dot and the coefficient dispersion.

The results show that the entanglement of field-atom reduced to a stationary value with time evolution and the entanglement between two modes increase to another stationary value with intrinsic decoherence, and the values only depend on the two-mode photon number and mean photon number.

The main contributions are as follows:(1) The decoherence suppression of N level Markovian systems is investigatedby the optimal control in the coherence vector representation. The N level Markoviansystem can be described by the master equation, and possesses a standard bilinear formin the coherence vector representation.
