In this thesis , how to use the lens - shaped quantum dot as a quantum bit will be reported 在这片论文里,我们将讨论利用透镜型量子点构造量子位。
By survey and mapping , the authors ascertain that the main bodies consist of two bulky lens - shaped bags of ore with 340 direction of dip and 70 80 angle of inclination 经矿区调研填图,圈定出主矿体是由两条呈倾向340 、倾角70 80的巨型扁豆状矿囊组成。
The binding energies and the ground state energies of hydrogen impurity in a lens - shaped quantum dot ( gaas / inl - xgaxas ) under vertical magnetic field using effective mass approximation and variation method have been discussed 利用有效质量近似、变分法,研究了垂直磁场下透镜型量子点( gaas / in1 - xgaxas )掺入类氢杂质后基态能和结合能。
( 2 ) for a lens - shaped quantum dot , due to the asymmetry of the bound potential of in - plane and perpendicular to the plane , the electric ground state energies are related not only with the deviation distance but also with the deviation direction ( 2 )对于透镜型量子点,由于水平方向和垂直方向束缚势不对称,电子基态能不仅与杂质的偏离距离有关,还与杂质偏离方向有关。
Firstly the binding energies and the ground state energies of hydrogen impurity in a lens - shaped quantum dot ( gaas / inl - xgaxas ) under vertical magnetic field will be displayed . then how to use the nuclear spin as the quantum bit will be given 首先研究了垂直磁场下透镜型量子点( gaas / in1 - xgaxas )掺入类氢杂质后基态能和结合能,然后讨论了如何利用量子点中杂质核自旋构造量子位。
