Best Brilliant Courses for Quantum Computing
8 Brilliant courses curated for the path into quantum computing. Interactive, visual lessons covering both the math prerequisites and quantum concepts themselves. A 7-day free trial covers the full catalog.
What to know about Brilliant for quantum computing
Brilliant is built around interactive puzzles rather than video lectures. Each lesson makes you click, drag, or answer something, which suits quantum concepts because so much of the difficulty is geometric, not a formula to memorise. Before you subscribe:
- Foundations first. The useful part, if you are heading toward Qiskit, Cirq, or PennyLane, is the math: linear algebra, complex numbers, and probability.
- Interactive Quantum Computing course. Brilliant's flagship Quantum Computing course covers qubits, gates, entanglement, and a hint of algorithms via puzzles. It is conceptually solid but does not teach you to write quantum programs - you'll need a framework-specific course for that.
- Free trial covers everything. The 7-day trial includes every course. Run a math course beside the Quantum Computing course during that week.
- Monthly or annual billing. Brilliant Premium is sold as a subscription with both monthly and annual plans. The annual plan works out far cheaper per month, so pick based on how long you expect to keep studying.
- Mobile-friendly. The puzzles work well on a phone, which makes Brilliant useful for short learning sessions during commutes or breaks - a niche the heavier video platforms don't fill as well.
Brilliant courses for quantum computing
All 8 courses, beginner first
-
-
Brilliant
Complex Numbers
Complex numbers, amplitudes, phases, and the complex plane, as interactive problems. This is the notation a qubit state is written in.
-
Brilliant
Computer Science Fundamentals
Search, sort, Big O, and graphs, as interactive problems on Brilliant. The same counting is what you use when a quantum algorithm has a cost.
-
Brilliant
Logic
Deduction puzzles on Brilliant: order, negation, and working through cases. The same habits show up in proofs.
-
Brilliant
Quantum Computing (Interactive)
Brilliant's quantum computing course uses puzzles and pictures. It sits inside a Brilliant subscription, and the free trial includes it.
-
Brilliant
Quantum Mechanics with Sabine
Brilliant / Sabine Hossenfelder
Quantum mechanics on Brilliant, with Sabine Hossenfelder. You work the simulations: states, superposition, and measurement.
-
Brilliant
Vectors and Matrices
Vectors, matrices, transformations, and eigenvalues, as interactive problems. The linear algebra used to write gates and states.
-
Brilliant
Group Theory
Group theory on Brilliant. Symmetries, and the algebra used to write quantum gates and error-correcting codes.
Brilliant vs other platforms for quantum computing
How Brilliant fits next to Coursera, edX, Udemy, and IBM Learning
Brilliant strengths
- Interactive puzzles build geometric intuition for qubits and gates faster than equations
- Excellent coverage of math prerequisites (linear algebra, complex numbers, probability)
- Mobile-first design supports short, frequent study sessions
- 7-day free trial with full platform access
- No prior knowledge assumed; lessons start from scratch
Brilliant limitations
- No coding component - won't teach Qiskit, Cirq, or PennyLane
- No verified certificates, unlike Coursera and edX
- Subscription-only pricing after the trial (monthly or annual)
- Conceptual depth is shallower than university-led courses
- Less suitable for advanced topics like fault tolerance or error correction
Frequently asked questions
- Is Brilliant good for learning quantum computing?
- Brilliant is strong for the foundations and intuition behind quantum computing. The interactive Quantum Computing course covers qubits, gates, superposition, and entanglement through visual puzzles rather than equations. It is excellent as a first exposure or alongside math prerequisites like linear algebra and complex numbers, but it does not teach you to write Qiskit, Cirq, or PennyLane code. Pair it with a programming-focused course once you have the conceptual base - browse our Coursera, edX, or Udemy selections for hands-on follow-ons.
- Can I use Brilliant for free?
- Brilliant offers a 7-day free trial of Brilliant Premium that includes every course on the platform. After the trial, Premium is a paid subscription with both monthly and annual plans; the annual plan has a much lower effective monthly rate. Brilliant also offers limited free previews of course content, which is enough to gauge whether a topic suits your level.
- Which Brilliant courses prepare you for quantum computing?
- Linear Algebra, Complex Numbers, and Probability are the three most important prerequisite courses. Quantum states are vectors in a complex Hilbert space, gates are unitary matrices, and measurement outcomes are probabilistic, so each of these maps directly to quantum mechanics. Group Theory and Algorithms are useful follow-ons once you progress to specific algorithms like Shor's and Grover's. Our prerequisites guide lays out the full sequence.
- How does Brilliant compare to a Coursera quantum specialization?
- Brilliant is faster to start and lighter on time commitment, but it does not match the academic rigour of a Coursera Specialization from a university. If your goal is a credential to put on a CV or graduate application, Coursera is the better choice. If your goal is to build mental models before tackling a heavier course, Brilliant is the better starting point.
