求翻译：操作完成后，Alice从制备的2n个团簇态中随机选取n个态作为校检序列，并记录其位置，然后对这n个校检序列随机执幺正变换I或H。是什么意思？

After the operation is complete, alice randomly selected from the preparation of the 2n-cluster state of n-state as the school inspection sequence and record its location, and then these n school inspection sequence random executive unitary transformation i or h.

After the operation is complete, Alice prepared from one of the suite 2n in N randomly selected a State, as the test sequence and to record its location, and then to the N of the test sequence is random practice else transform I or H.

After the operation completes, Alice condition selects n from the preparation 2n group bunch condition to examine the sequence stochastically as the school, and records its position, then examines the sequence to these n school to hold the unitary transformation stochastically I or H.

When the operation is complete, Alice from 2n for preparation of a random n-State in the cluster state as a checking sequence, and records its location, this n-test sequence and unitary transform in random practice I or h.
