两能级原子作为量子存储单元,当存储单元置于压缩真空库(人工制备的库)时,利用存储单元约化密度算符非对角元的时间演化,研究单光子过程和简并双光子过程中存储单元的消相干特性.在压缩真空库中,可以消除量子存储单元的消相干.

The two-level atom is regarded as quantum memory cell when the quantum memory cell is put in a squeezed reservoir. Using the time evolution properties of non-opposite angle element of quantum memory cell's reducible density rectangular array, decoherence properties of quantum memory cell is studied. Quantum memory cell's decoherence can be el...
