You can start learning quantum computing with a simulator on an ordinary computer; you do not need to buy hardware or set up a cloud account first. Learn qubits, gates, measurement, and entanglement, choose one programming route, then build and test a small circuit. For most beginners, the practical choice is between Python-oriented Qiskit materials and Microsoft’s guided Q# path; AWS Braket is worth considering when cloud-service onboarding is itself part of your goal.
Start with the circuit model, not hardware
Quantum computing uses quantum-mechanical behavior for some computational tasks. A useful first step is to understand the basic vocabulary and how a circuit represents computation:
- Qubit: the basic unit of quantum information. Its state is described differently from a classical bit, which is either 0 or 1.
- State: the information represented by a qubit or group of qubits. Learn how a state changes when an operation is applied.
- Gate: an operation on one or more qubits. In a circuit diagram, gates are arranged in sequence.
- Measurement: the process of obtaining a classical result from a quantum state. Repeating a circuit can help you observe the distribution of outcomes.
- Entanglement: a relationship between qubits that cannot be explained by treating each qubit as an independent state.
IBM Quantum Learning’s course catalog includes foundational quantum information material covering states, measurements, circuits, and entanglement. Microsoft Learn also offers a beginner path on quantum computing fundamentals. A basic grasp of linear algebra will help, but you can begin with the introductory concepts and small exercises rather than mastering the mathematics first.
Choose one learning and programming route
Pick a single ecosystem for your first course and project. Switching among providers before you have built a circuit adds setup and terminology without helping you understand the fundamentals.

| Route | Best fit | What the official material covers | What to expect |
|---|---|---|---|
| IBM Quantum Learning and Qiskit | Learners who want quantum-information concepts alongside Python-oriented quantum programming materials. | The IBM Quantum Learning catalog lists courses in foundational quantum information, quantum algorithms, general quantum information, and error correction. The Qiskit tutorials include a Get started section for first-time users. | A simulator-first start is suitable. Use the current course catalog and tutorials; IBM’s former Getting started with Qiskit learning path now redirects to a page stating that the path no longer exists. |
| Microsoft Learn, Q#, and Azure Quantum | Learners who prefer a guided sequence with explicit exercises. | The Microsoft Learn beginner path covers fundamentals, a quantum random-number generator, superposition, teleportation, and resource estimation. | Microsoft lists basic linear algebra, familiarity with Visual Studio Code, and basic Azure ecosystem knowledge as prerequisites. The path connects Q# with the Quantum Development Kit and Azure Quantum. |
| AWS Braket | Learners whose specific goal is to explore AWS’s quantum cloud service. | AWS’s Braket getting-started documentation points to its Digital Learning Plan and setup steps such as enabling Braket and creating a notebook instance. | Cloud setup differs from local simulation. Check current service access, regions, device availability, and costs before submitting jobs; the getting-started page does not establish current pricing. |
IBM’s route pairs conceptual material with Python-oriented tools. Microsoft’s is more explicitly exercise-led and calls out platform prerequisites. Braket is most directly oriented toward AWS service onboarding. Microsoft describes its own offering as “the best combo to start exploring quantum computing” in the Learn page, “Get started with Azure Quantum”; treat that as Microsoft’s positioning, not an independent comparison.
Build a first project in a simulator
Use a small circuit to connect the ideas to code. A simulator lets you examine expected behavior without waiting for access to a remote device or dealing with hardware-specific constraints.
Rank #2
Option 1: Generate and inspect a quantum bit
Microsoft’s beginner path includes a Q# quantum random-number generator exercise. Use it as a first coding task: run the exercise, inspect how the circuit produces an outcome, and repeat it. A single result is not proof of a perfect or independently verified source of randomness.
Option 2: Explore superposition and measurement
In Microsoft’s superposition lesson, prepare a single-qubit state and measure it repeatedly. Before running the circuit, write down what outcomes you expect and how often you expect to see them. Compare that expectation with the simulator’s distribution; individual runs can differ from the overall pattern.
Option 3: Demonstrate entanglement and teleportation
Microsoft’s path includes an exercise on entangled qubits and teleportation. Treat it as a circuit-level demonstration of the protocol. Quantum teleportation does not enable faster-than-light communication.
Next challenge: Try the CHSH inequality tutorial
Once you understand basic gates and measurements, IBM’s Qiskit tutorial index lists a CHSH inequality tutorial in its beginner-oriented Get started section. It is a more ambitious step than a single-qubit exercise because it brings together multiple measurements and correlations.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Check what the circuit does, then change one thing
For a first project, follow a simple loop rather than adding complexity immediately:
- State the expected behavior. Describe the outcome you expect from the circuit before running it.
- Run the small circuit in a simulator. Check whether the measurement behavior matches your expectation.
- Change one variable. Try a different gate, input state, or number of repetitions, but not all at once.
- Record and compare. Note what you changed and how the simulator output differed from your prediction.
- Move to hardware only if useful. Once you understand the circuit, follow the provider’s current instructions to explore a cloud device if access is available.
A published teaching report describes a similar progression from single-qubit systems and measurements to entanglement, teleportation, simple algorithms, debugging, and hardware exploration. It also notes that cloud-device jobs can involve significant waits. Remote hardware is an optional extension, not a prerequisite for understanding the concepts.

What you need—and what not to expect
- No quantum computer is required. An ordinary computer and a simulator are enough for the first concepts and projects.
- Linear algebra is useful. Microsoft explicitly lists basic linear algebra as a prerequisite, along with Visual Studio Code familiarity and basic Azure ecosystem knowledge.
- Keep early exercises small. This makes it easier to reason about the circuit and spot mistakes before introducing device-specific constraints.
- Do not expect a general speedup. Introductory examples are demonstrations of quantum ideas, not evidence that quantum computers outperform classical computers on ordinary everyday workloads.
Optional reading alongside the free learning materials
A beginner quantum computing textbook or quantum computing workbook can provide a structured reference and exercises alongside courses. A 2021 undergraduate teaching paper describes reproducible Qiskit code and material intended to help readers carry out their own projects, which supports using a book as an adjunct—not as a required purchase or a guarantee that a particular title remains current. See Fernandes de Jesus et al., “Quantum Computing: an undergraduate approach using Qiskit”. Another teaching report discusses the Microsoft Quantum Development Kit and Azure Quantum: Mariia Mykhailova, “Teaching Quantum Computing using Microsoft Quantum Development Kit and Azure Quantum”.
