Quantum cryptology is a new method for secret communications. Compared to the classical cryptography, the greatest advantages of quantum cryptography are provable security and detectives; this is because the security of quantum cryptography is ensured by quantum no-cloning and Heisenberg's uncertainty principle that instead of relying on some complex mathematical problems.

The quantum amplitude amplification is the generalization of quantum Grover search algorithm. In this strategy, the Grover iteration has been replaced by two different quantum amplitude amplification operations. This makes it possible to collapse the system with probability 1, in other words, with certainty. The measurement operation in this scheme is only used to cancel the phase factor. Finally, one can use the admissible control to drive the system from the eigenstate to the target state and the control task is accomplished.

量子幅值放大是Grover迭代思想的一般化，该控制方案中采用两种不同的量子幅值放大操作替换了Grover迭代，使得期望本征态的概率幅的模在经过一定次数的迭代之后精确的等于1，然后借助于测量来消除相位因子，使系统的波函数确定性的塌缩到期望的本征态，最后再借助幺正演化，将系统从本征态控制到目标态，实现期望的控制任务。

By the historical and methodological pondering over the development process of modern physics,based on the research work done by Arndt,Zurek,Brune,Myatt and so on,the problem of the wave-particle duality,the boundary between classic physicsand quantum physicsand the quantum decoherence of object particles is extended to the boundary of electromagnetic fields between classic and quantum in this paper.

Have already perplexed people for morethan 100 years. In order to have solution of quantum mechanics problem, I have spent 43years in these issues. I thought that I have perfectly resolved a series of "hypothetical problem" of the quantummechanics, giving a quite good answers to a series hypothesis like quantum, Planckconstant, De Broglie relation, uncertainlyrelation, electron angular momentum etc. The answer is that Quantum mechanicschange into "Electronphysics". This is a greatleap in the development of physics.
