Wave Function Collapse
Quick fact
The act of measuring a quantum system causes its wave function to collapse into a single definite state.
Why this is interesting
Imagine a coin spinning in the air—until you catch it, it’s both heads and tails. But once you look, it settles into one state. This is how quantum systems behave.

Understanding Wave Function Collapse
In quantum mechanics, particles exist in multiple states at once—this is called superposition. When you measure the particle's property (like position or momentum), it 'chooses' one state, and this process is known as wave function collapse. It’s like flipping a coin that only lands on heads or tails when you look.
A deeper explanation
Wave function collapse occurs due to quantum measurement, which interacts with the system and forces it into an observed state. This process explains how probabilities in quantum mechanics become actual outcomes. The collapse is not random but follows probabilistic rules defined by the wave function itself.
