For Enthusiasts

Create quantum entanglement from your desk

The first desk toy that lets you control a real quantum computer.

Like a lava lamp... but quantum

Beautiful visuals that represent true quantum behaviors. Yes, the colors mean something.

595 full-gamut RGB LEDs create a living, breathing display of quantum states. Watch superposition swirl, see entanglement correlate, and witness measurement collapse in real time.

Frequently Asked Questions

Two Qubi spheres, a USB-C charging cable, a quick start guide, and access to the free Qubi app with 30+ activities, the Qubi Arcade, and Qubi Studio.

Entanglement is a two-qubit phenomenon. Many activities require a pair — you entangle them, separate them, and observe correlated results. It's also more fun with a friend.

Qubi connects to your phone via Bluetooth. WiFi is only needed for firmware updates and sending algorithms to real quantum computers.

About 4 hours of active use. Charges via standard USB-C. The ambient light sensor adjusts brightness to save power.

Not at all. The app guides you from zero knowledge through real quantum concepts. No math, no equations — just hands-on exploration.
