What did I just read? "Any noise or unintended observation of them can cause data loss." Unintended observation?

Yes, if you observer the system, it gets disturbed. It's like opening Schrodinger's box to see the cat.

"Observation" in the quantum-mechanical sense, i.e. "interaction with the state of the outside world".

Measurement requires interaction with the system, and interaction with the system breaks entanglement.

Or, more precisely, alters entanglement in an unkown way. Since the alteration is unkown, it interferes with execution and interpretation of the quantum algorithm.

I found this video on quantum mechanics helpful.

If you measure the qubit prematurely the function collapses. In classical computing it might be analogous to breaking out of a for loop before it has run its intended course and then you're left with an incorrect (or incomplete) answer.
