# Qolour — Qubi

> Qolour makes Qubi, the world's most beautiful qubit. Qubi is a handheld, interactive quantum computing simulator that lets anyone — from 13-year-old kids to Caltech professors — learn quantum computing, entangle devices, replicate Nobel-prize-winning experiments, and program real quantum computers over the cloud.

Qubi is a physical model qubit: a 90mm sphere with 595 full-color LEDs that visually represents a quantum state on the Bloch sphere. Shake it to measure. Twist it to apply a gate. Bump two Qubis together to create entanglement. Connect through the Qubi app to run circuits on real IBM and IonQ hardware.

Built by a team of former Apple, Berkeley, UMD engineers and guided by John Preskill (Caltech), Iordanis Kerenidis (Paris Centre for Quantum Technologies), and Yasser Omar (University of Lisbon).
