quantum measurement problem

The quantum measurement problem arises from the peculiar behavior of particles at the quantum level. When we observe or measure a quantum system, say an electron, it appears to 'choose' a specific state from a range of possibilities. Before measurement, the electron exists in a superposition of multiple states. The act of measuring causes this range of possibilities to collapse into one definite outcome. This raises questions about the nature of reality and the role of observation: does the act of measuring determine a state, or does the particle have a specific state all along, independent of measurement?
