The first decision you'll ever make that wasn't predetermined.

Name two options. A real quantum measurement chooses between them for you. Nothing in the universe could predict the outcome.

One particle. Two paths. Break the chain of cause and effect.detections 0
One free measurement a day

How it works

  1. Pick two optionsOption A and Option B. Written down or kept to yourself.
  2. We measure a quantum particleNothing in the universe can predict the result.
  3. It picks a sideTop means A. Bottom means B.

Why quantum

According to classical physics, everything in the world follows cause and effect. Physicists call this view of the universe "deterministic."

A quantum measurement is the one outcome physics says cannot be predicted, even in principle. Basing a decision on a quantum measurement is as close as you can get to guaranteeing your own free will.
