Hands-on tracks that take you from “what even is a qubit” to running circuits on real quantum hardware — no local setup required to start.
Quantum foundations
A free five-lesson course on the foundations of quantum computing: qubits, gates, matrices, and complex numbers. About an hour, no account needed.
from qiskit import QuantumCircuit qc = QuantumCircuit(2) qc.h(0) qc.cx(0, 1) qc.measure_all() # run it on real IonQ hardware
Building your first Qollab project
Create your first project on Qollab and run quantum circuits live in your browser, with nothing to install. A short, hands-on walkthrough.
Quantum computing with Python and Qiskit
A free, hands-on course: set up Python and Qiskit locally, write your first quantum circuits, and run them on a simulator and real hardware.
Concepts
Understanding Quantum Superposition
Putting a register into sixteen million states costs twenty-four gates. Getting an answer out of it is the hard part, and that gap is what superposition actually is.
Understanding Quantum Measurement
Measurement does not read a value off a qubit, it produces one. Why a single run tells you nothing, and why the question you ask changes the answer.
Understanding Quantum Interference
Superposition on its own is indistinguishable from a coin. Amplitudes are signed, they cancel, and that cancellation is the only reason an algorithm lands on the answer you want.
Building with Quantum Entanglement
What entanglement means, where the idea came from, and real projects built on it that you can run and fork.
