Quantum logic gate and quantum logic operation method using exciton |
摘要 |
A quantum logic gate utilizes an inter-polarization (dipole-dipole) interaction between excitons having polarization in semiconductor quantum well structures, or a spin exchange interaction between spin polarized excitons in the semiconductor quantum well structures. Problems associated with conventional semiconductor quantum well structures are solved in that a phase relaxation time is very short because of using inter-subband electrons, and that there is no usable ultrashort optical pulse laser technology because a subband transition wavelength is in a far-infrared region and hence ultra fast control is impossible.
