Qubi is a quantum physics-inspired desk toy that mimics real qubits. Use it to experiment with science's strangest paradoxes and algorithms, screen-free.
Quantum paradoxes to discover
Beautiful unlockable themes
Hours saved vs. traditional quantum learning
Qubi puts the elegance of quantum mechanics where you can see it, touch it, and share it.
Most people think quantum is confusing because they haven’t seen anything that acts quantum.
See what Qubi was built to mimicIncluded with Qubi: Explore the foundations, learn how to program a quantum computer, and ponder the philosophical implications of quantum physics.
Entanglement feels paradoxical—even Einstein called it “spooky.” Qubi lets you experiment with the correlations instead of just reading about them.
Hover over the spheres below to watch matching colors jump between qubits whenever a measurement collapses one of them.
Entangled qubits
The people building the quantum future are already using Qubi to explain the Bloch sphere, demystify algorithms, and bring more minds into the field.
PhD Candidate, Duke Quantum Center
“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.”
PhD UC Berkeley, Postdoc MIT
Founder, Paris Center for Quantum Computing
“It’s time to stop calling quantum ‘counterintuitive.’ Qubi makes it make sense.”
Director, Quantum Startup Foundry
“Qubi is the clearest way to visualize quantum systems and has a chance to revolutionize how we communicate (quantum) concepts. It just makes sense. It’s obviously a fantastic way to bring quantum into more minds.”
Explore the strangest and most counterintuitive discoveries—from teleportation to nonlocality.
Observe how quantum computers can crack encryption, transmit data securely, and more.
Send jobs to live quantum hardware straight from the Qubi app. Watch the results appear on your qubis, alongside guided explanations that decode what just happened.
Stay up-to-date on the current state of quantum computing and science. Benchmark new processors, compare noise profiles, and understand which algorithms succeed today.

Qubi is a unique and memorable gift for any science lover. It's great for kids and adults alike.
“It’s so nice to finally see something (quantum) that’s down-to-earth and accessible.”
Josephine D. | Quantum Technologies Consultant
“I think Qubi is simply a brilliant idea for introducing many people to the principles of quantum.”

No. Qubi will teach you all you need to know. Ages 8+ can follow the guided lessons. Qubi is designed for complete beginners and includes step-by-step learning modules that make quantum concepts accessible to everyone.
No, but the spheres act like the mouse for a real quantum computer. Whatever you do on the spheres will be run on a real quantum computer and sent back to you. You're controlling actual quantum hardware through an intuitive interface.
While qubi is fun to play with and will survive reasonable drops, it's not designed to be thrown at a wall. It's a bit more durable than a cell phone.
You can check the pricing on the kickstarter page! Early-bird backers get lower prices, and they run out fast - so it's hard to keep pricing updated on this page.
You can pre-order starting October 14th, and we will do our best to get you your Qubis before Spring 2026!
