Quantum mechanics depicts a counter-intuitive reality in which the act of observation influences what is observed — and few can agree on what that means.

Quantum coherence is an interference between these different possible future histories of the object. However, this interference can exist only until the system is observed or disturbed.

Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not being directly observed.
