What People Are Saying
From Caltech professors to high school students
“Qubi is the world's most beautiful qubit”
John Preskill
Professor of Theoretical Physics, Caltech
“It's time to stop calling quantum 'counterintuitive.' Qubi makes it make sense.”
Iordanis Kerenidis
Founder, Paris Center of Quantum Computing
“Everyone has some visual reasoning skills that can be engaged to teach Bloch sphere representation of qubits. Using a tangible, interactive sphere maximizes that engagement. It provides an access point for anyone, even kids. This is the most intuitive learning tool for teaching qubits I've seen.”
Denton Wu
PhD Candidate, Duke Quantum Center
“This is revolutionary.”
Yasser Omar
Creator, World Quantum Day
“I think Qubi is simply a brilliant idea for introducing many people to the principles of quantum computing. I will definitely be ordering a set.”
Lars Heimann
CEO, anabrid
“This makes learning quantum computing infinitely faster.”
Deva Menon
Undergraduate, University of Maryland
“Every high school should have one of these”
Tomás Fernández Martos
Researcher, Quside & Universitat de Barcelona
“Qubi is the clearest way to visualize quantum systems and has a chance to revolutionize how we communicate concepts. It just makes sense.”
Piotr Kulczakowicz
“The Qubis presents quantum information in a clear and approachable way, which I believe is essential for introducing the next generation to the field.”
Lara De
High School Student
“They are pleasing to the eye and intuitive!”
Marc Poulton
University Freshman
Frequently Asked Questions
Qubi is a pair of wirelessly connected interactive spheres that make quantum science tangible. Each sphere is a physical model of a qubit — the fundamental unit of quantum computing. Shake to measure quantum states, twist to apply rotations, and bump them together to create entanglement. A guided app walks you through everything from the basics to real quantum computer experiments.
Preorders are expected to ship in June 2026. We'll send email updates as we get closer to the ship date. US shipping is free; international shipping rates are calculated at checkout.
Qubi is designed for ages 13 and up. The guided app includes content suitable for younger learners as well as advanced material for university students and professionals. No prior physics or quantum computing knowledge is needed.
Yes — Qubi pairs with the free Qubi app (available on iOS and Android) via Bluetooth. The app provides guided lessons, interactive experiments, and a connection to real quantum computers. The Qubis auto-connect when you open the app.
Yes! Through the app, you can send quantum algorithms to real quantum hardware and see the results played back on your Qubis. This lets you compare your hands-on experiments with real quantum computer behavior.
Each Qubi has a 1200mAh LiPo battery that provides approximately 4 hours of active use off the charging stand. They charge via standard USB-C.
Yes. You can cancel your preorder for a full refund at any time before your order ships. Visit our preorder policy page for full details, or contact us at hello@qolour.io.
The app includes three modes: Qubi Spark (guided learning platform with chapters and mini-lessons), Qubi Arcade (quantum games and challenges), and Qubi Studio (advanced quantum operations for deeper exploration). All are included free with your Qubi purchase.
