It contains a nested loop that calls exp , cos , and sin , followed by a loop that calls sin and SQRT .

它包含了一个嵌套的循环，该循环会调用exp 、cos以及sin，接下来是一个调用sin和sqrt的循环。

the amplitudes for base states where x is |1> are multiplied by exp(i*a)=cos(a)+i*sin(a).

x是 |1>的基态振幅乘上了exp(i*a)=cos(a)+i*sin(a)。

Transcendental mathematical functions (such as pow, exp, log, cos, sin, tan, etc) will tax the GPU greatly, so a good rule of thumb is to have no more than one such operation per fragment.

一些超越数学函数(如pow,exp,log,cos,sin,tan等)将增大GPU计算的负担，所以一个好的法则就是在每个片段中使用不多于一次的这种操作。
