Based on a magnetic field controlled electron spin quantum system, utilizing the mechanism of realizing the unitary evolution of the quantum state through the quantum gate, an optimal control strategy to prepare an arbitrary quantum state is proposed
摘要針對以磁場為控制場的電子自旋量子比特系統，結合量子門實現量子態么正演化的量子態調控機制，提出了一種量子比特系統任意量子態的最優制備策略。 -
The effects of the operation temperatures, gate voltages, drain - source voltages and magnetic field upon the characteristic of device are analyzed in detail. coulomb blockade and single electron tunneling are observed in the devices. 3
詳細地分析了工作溫度、柵極電壓、漏源電壓和磁場對其特性的影響，觀測到明顯的庫侖阻塞效應和單電子隧穿效應，器件的工作溫度可達到77k以上。 -
The main works and results we have accomplished are as follows : 1 ) red - detuned locking of cooling / trapping laser to the cycling transition of cesium cooling has been accomplished by means of a double - passed acoustic - optical frequency shifting system and the technique of saturated absorption spectroscopy. the short - term residual frequency jitter is less than 350khz ; 2 ) automatic controlling system by computer programs has been established for laser cooling and trapping and cavity qed experiment. the laser and magnetic fields can be controlled by the acoustic - optical modulator and the electronic - controlled logic gate respectively
具體如下： 1 ）採用了往返兩次通過的聲光頻移系統結合飽和吸收光譜技術的實驗方案，實現了冷卻俘獲激光頻率相對于銫原子冷卻循環躍遷的負失諧鎖定，短期頻率穩定度約在350khz以內，並可方便地調節其負失諧量而無須對后續光路再作調整； 2 ）建立了一套基於計算機程序控制的、銫原子激光冷卻與俘獲實驗所需的時序控制系統。 -
