Can something be dead and alive at the same time? Or here and there? Or active and quiet? Learn here about the principle of superposition!

Main takeaways

• Superposition is a fundamental principle of quantum mechanics.
• Quantum states can be added together – superposed – to yield a new valid quantum state.
• Every quantum state can be seen as a linear combination, a sum of other distinct quantum states.

Superposition can be visualized by an experiment, where you shoot quantum particles through two slits.

Main takeaways

• In the double slit experiment a classical bit chooses either one of the openings.
• The qubit can be put in a superposition of both paths.

Another experiment that shows the power of a quantum computer is the maze. What is the advantage of superposition compared to a classical way of computing?

Main takeaway

• Quantum computers are good at solving search tasks.
