WHAT IS QUANTUM?
Classical computers store information as bits — a strict 0 or 1. Quantum computers use qubits, which can exist in a superposition of both states at once, and can be entangled so that qubits become correlated no matter how far apart they are.
By manipulating these quantum properties with precisely tuned operations called quantum gates, we can explore many possibilities simultaneously — unlocking new approaches to chemistry, optimization, cryptography, and machine learning.
It isn't magic, and it doesn't replace classical computers. It's a fundamentally different way of processing information, built on the strange rules that govern the universe at its smallest scale.
Core Domains in Quantum

What makes a quantum bit different?
A classical bit is always a strict 0 or 1. A qubit — built from a superconducting circuit, a trapped ion, or a photon — is governed by quantum mechanics instead, giving it abilities no classical bit has, like superposition and entanglement.

GETTING STARTED
Ready to go beyond theory? The best way to learn quantum computing is to write and run real quantum circuits.
Start with IBM Quantum Learning for guided courses, spin up your first circuit on the IBM Quantum Platform, and follow along with Qiskit's documentation as you build.
Then join us at Qiskit Fall Fest Nairobi — our workshops walk you through every step, from your first qubit to your first quantum program.
