What of importance of superposition in quantum computing?

What I understood is we have two states |0> and |1> which represent logical 0 and 1 . So the mixed state can be given by the combination of logical operators like OR, AND and NOR Etc. For example

1/3 |0>+2/3 |1>

The particle could be in either of the two states. Each time when you measure the particle it is found in one of the state. The probability of falling in one state or another state is somehow written in superposition.

Is it correct? What is the exact explanation?
