Qubit is a game played in a court made of the laser beams, controlled by a quantum computer. Qubit challenges you to predict the speed or location of a particle (since you can’t know both)

Your objective is to win – probably.

The game is played in the centre of a court made from four lasers. The lasers are aimed at sensors so we can detect when the beams are broken.

At the start of each round we release a virtual particle in to the circuit. This virtual particle travels along the laser beams at an unknown speed. The conceit of the game is that at any time we can narrow down the virtual particle’s position to one of two beams. The players then have to guess which of the two beams the particle is in and try to observe it, using a Hand Held Observation Platform (HOOP). At 15-second intervals players have to roll their hoop into the path of the beam they think contains the virtual particle. If they get it right then the Qubit will calculate a point for them. If they get it wrong they lose the HOOP.

How it Works

Qubit takes the sometimes frightening world of the quantum and makes it playable with a hoop. The game uses a laser interferometer as a single bit in a quantum computer. We use this qubit as a score calculator.

Specifically, Getting a hoop in the right beam at the right time will set off a vibration motor that wobbles the superpositioned beams coming out of the interferometer. There is a camera monitoring these beams. When the signal is analysed, it lets us know when we have a stable state and when it collapses.

The game is simple to play and acts as a rabbit hole, a way for people to develop an understanding and an interest in quantum physics.
