Quantum Superposition: How Particles Exist in Many States

Quantum superposition means particles can exist in multiple states at the same time.
An electron can be in two places—or spin in two directions—until it’s measured.
Measurement collapses the superposition into one definite outcome.
Schrödinger’s Cat is the most famous illustration of this concept.
Superposition allows quantum computers to process many possibilities at once.
Unlike classical bits (0 or 1), quantum bits can be 0, 1, or both simultaneously.
Interference patterns in experiments prove particles exist in overlapping states.
Superposition only shows up at tiny, quantum scales—not in everyday objects.
It reveals that probability, not certainty, rules the quantum world.
Superposition is one of the key mysteries that makes quantum physics so powerful—and strange.
