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.

In the quantum world, things don't work quite the same way. Quantum superposition describes how a quantum particle, like an electron, a photon, or even an atom, can exist in multiple different ...

For today’s Doodle, Google uses a spinning thaumatrope disc to communicate the basics of quantum superposition. When Google’s trying to come up with a theme for its latest Doodle, it’s not ...

and the object is in an undefined state known as a superposition. Schrödinger’s thought experiment probed how this plays out when a quantum object is coupled to something more familiar.
