To run your first quantum experiment
No math, physics, or coding required
Send circuits to actual quantum computers
Qubi is a handheld quantum simulator that takes you from basics to real quantum computing through guided lessons.
Explore the foundations, learn how to program a quantum computer, and ponder the philosophical implications of quantum physics.
Chapter 1
Foundations
Use Qubi to build intuition for states, amplitudes, and measurement without needing heavy math first.
The people building the quantum future are already using Qubi to explain the Bloch sphere, visualize algorithms, and make the field more accessible than ever.
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.”
Built in collaboration with:
See superposition, entanglement, and measurement in real-time on a glowing sphere you can hold. Guided experiments make concepts stick through hands-on exploration — don't memorize, understand.
Explore a whole cookbook of algorithms that matter right now. Understand how quantum computers can crack encryption, transmit data securely, and more.

Write circuits in the app, send them to IBM or IonQ hardware over the cloud, and see results on your Qubi. Not a simulation — your code runs on real quantum processors.
Compare noise profiles, benchmark different machines, and see which algorithms succeed on today's hardware — with guided explanations of what just happened.
Quantum Computing with Qubi
Perfect for classrooms, workshops, or explaining quantum to friends and family. Qubi gives students a tangible way to grasp abstract concepts — no equations on the board required.
Qubi for EducatorsExplore the strangest and most counterintuitive discoveries—from teleportation to nonlocality.
Ready out of the box
Qubi acts like a qubit right out of the box. No setup required.
Qubi is a striking object that brings the magic of quantum into your space. Place it on your desk, shelf, or table and watch it spark curiosity and conversations with everyone who sees it.
Qubi is a collaboration with researchers, educators, and labs who care about educating the public about quantum.
The Science behind Qubi
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 is designed for complete beginners with zero prerequisites. The guided curriculum teaches quantum concepts through hands-on interaction, not equations. Ages 8+ can follow along.
You can run your first quantum experiment in about 5 minutes. The full curriculum is self-paced and covers everything from basic concepts to programming real quantum computers. Most users feel confident with the fundamentals within a few sessions.
Qubi is a quantum simulator — physical hardware that accurately models how qubits behave. What makes it special is that you can connect to real quantum computers (like IBM and IonQ) over the cloud. Build circuits on your Qubi, send them to actual quantum processors, and see the results come back to your device.
Online courses teach through videos and text — you watch and read. Qubi teaches through physical interaction — you learn by doing. When you tilt, rotate, and manipulate the sphere, you see quantum states change in real-time. This hands-on approach makes abstract concepts intuitive and memorable.
Quantum computing uses the principles of quantum mechanics — superposition, entanglement, and interference — to process information in fundamentally new ways. Unlike classical computers that use bits (0 or 1), quantum computers use qubits that can exist in multiple states simultaneously, enabling them to solve certain problems exponentially faster.
A qubit (quantum bit) is the basic unit of quantum information. Unlike a classical bit that is either 0 or 1, a qubit can be in a superposition of both states at once. Qubits are represented on a Bloch sphere, where any point on the surface represents a valid quantum state. Qubi lets you physically interact with a Bloch sphere to build intuition for how qubits work.
Yes. Qubi is designed for ages 8 and up, making it perfect for middle school and high school students. The guided lessons start with the basics and progress at your own pace. Teachers can integrate Qubi into physics, computer science, chemistry, and math curricula with ready-made lesson plans aligned to ITSE and NGSS standards.
Quantum computers can solve problems that are practically impossible for classical computers — from simulating molecules for drug discovery and materials science, to optimizing logistics, strengthening cryptography, and advancing artificial intelligence. As these machines mature, quantum literacy will become essential across science, engineering, and policy.
