Learn quantum computing with tested code

Free quantum computing guides, tested Qiskit, Cirq and PennyLane example packages, and interactive lessons with an in-browser quantum circuit simulator.

Quantum Store was founded by software engineer Hakan Erdoğan. It offers 31 free packages, each with example code that has been run and verified, installation steps and the original licence, plus two interactive courses (beginner and intermediate) whose circuits run right in your browser.

Courses

• Beginner course · 6 lessons
  Qubits, superposition, measurement, entanglement and interference with no physics or maths background, ending with your first quantum algorithm.
• Intermediate course: quantum algorithms · 6 lessons
  From phase and the Bloch sphere to Deutsch–Jozsa, Bernstein–Vazirani, Grover, the quantum Fourier transform and phase estimation.

Guides

• What is a quantum computer and how does it work?
  What a quantum computer is, how qubits differ from bits, what quantum computers are good for and where they stand today. A plain-language guide, no physics needed.
• Getting started with quantum programming: your first Qiskit circuit
  How to start quantum programming: installing Qiskit, writing your first quantum circuit (a Bell state) and what to learn next. A step-by-step guide for Python developers.
• Quantum cryptography: how do quantum computers affect encryption?
  Can quantum computers break encryption? Shor’s and Grover’s algorithms, post-quantum cryptography (ML-KEM, ML-DSA) and quantum key distribution (BB84) explained.
• What is quantum machine learning?
  What quantum machine learning is, how it works and whether it really helps: variational circuits, quantum classifiers, realistic limits and first steps with PennyLane.
• How are quantum computers built? Qubit types compared
  Superconducting qubits, trapped ions, neutral atoms, photons and spin qubits: what quantum computers are made of, who chose which path, and the pros and cons.
• Quantum algorithms: what each one does and how it works
  The most important quantum algorithms in plain language: Deutsch–Jozsa, Bernstein–Vazirani, Grover, the quantum Fourier transform, phase estimation, Shor, VQE and QAOA.
