FYI, Superposition refers to the ability of a quantum system to exist in multiple states simultaneously until it is measured or observed. Unlike classical systems, which are in a single definite state, quantum systems can be in a combination of all possible states at once.
Example of Superposition:
One of the most famous examples of superposition is Schrödinger’s Cat thought experiment. Though this is a hypothetical situation designed to explain quantum mechanics, it captures the concept of superposition:

  • Imagine a cat inside a sealed box, with a mechanism that can kill the cat depending on the decay of a radioactive atom. If the atom decays, a poison is released, and the cat dies; if it doesn’t decay, the cat lives.
  • According to quantum physics, until someone opens the box and observes the state of the cat, the cat is considered to be in a superposition of both “alive” and “dead” states simultaneously. It’s only when an observation is made that the superposition collapses into one of the two definite states—alive or dead.
