Parallelizing quantum manager server

[xwu64]

Current implementation lets processes share a dictionary to record the quantum state. However, the shared dictionary will lock if one process is reading or writing the whole dictionary. This lock may affect the performance of parallelization.

states = manager.dict()

We hope to design a new shared data structure to avoid unnecessary lock.
