1) su(2) coherent state
su(2)相干态
1.
When the two-mode field is in the unrelated pure states at the initial moment,the linear entropy of the atom is always equal to the linear entropy of the coupled mode;when the initial state of the two-mode field is in SU(2) coherent state, the linear entropis of the atom and the coupled mode are no longer always the same.
当双模腔场初始时刻处于无关联的纯态时,原子与腔场中耦合模的线性熵始终相等;当双模腔场的初态处于SU(2)相干态时,原子与耦合模的线性熵不再始终相等。
3) generalized SU(2)coherent state
一般 SU(2)相干态
4) Dressed SU(2) coherent state
修饰SU(2)相干态
5) photon added SU(2) coherent state
加光子双模SU(2)相干态
6) su(1,1) coherent state
su(1,1)相干态
1.
The nonclassical light field in two-mode SU(1,1) coherent state has the predominant property in the entanglement between two modes, so theoretically speaking it can act as information carrier in quantum communication.
非经典光场SU(1,1)相干态具有较好的模间纠缠性质,可以作为量子通信的信息载体。
补充资料：相干散射和非相干散射
再辐射的光量子频率和被吸收的光量子频率准确相等的散射过程称为相干散射。在相干散射的情况下，源函数准确地等于平均辐射强度。再辐射的光量子频率和被吸收的光量子频率不相等的散射过程称为非相干散射。在天体物理中，存在一系列因素使散射过程成为非相干散射。主要的因素是：原子的能级有一定的宽度、原子的热运动和湍动以及压力效应等。对于非相干散射，源函数是相当复杂的。
