To round out the set and allow for universal quantum computation, we need the Controlled Phase function, CPhase .
要使集合完整并考虑普遍的量子计算,那么我们需要受控相位函数,CPhase 。

Then MapReduce shuffles the map output by key and does another parallel computation on the redistributed map output, writing the results to the file system in the Reduce phase of the computation.
