Became Hot Network Question

If I have understood correctly it's how with, in time a single qubit in superposition will collapse on it's own to the 0$|0\rangle$ or 1$|1\rangle$ state, but I thought it only collapsed when measured. How is the collapse explained if there isn't any measurement?

What is qubit decoherence?
