Meanwhile the phenomenon of the macroscopic quantum tunneling is also a decay process of metastable state.

而宏观量子隧穿现象同时又是一个亚稳态的衰减过程。

The system is in the state of the superposition of the two macroscopic quantum states. Thecoherent tunnelling between them leads to the energy splitting.

系统处于这两个宏观量子态的相干叠加态，它们之间由于相干隧穿导致能级的劈裂。

We explain how to realize macroscopic quantum coherence, namely the superposition of Schrdinger cat states and quantum phase interference by means of quantum tunneling.

文章作者解释了如何通过量子隧穿实现宏观量子相干(即薛定谔猫态的相干叠加)和量子态位相干涉。

Wavefunctions are what make the microscopic world of quantum physics appear so different from the macroscopic world that people operate in.
