How to Start Studying Quantum Computing from Scratch (Without Being a Physicist)

Quantum computing may seem like a distant and complex field, usually associated with physicists and mathematicians. However, with the growth of the technology, more resources are becoming accessible for anyone interested, even without a specific background in physics. If you’re a programmer, student, or technology enthusiast, and you want to start your journey in quantum computing, this guide is for you.

The good news is that you don’t need to be a physicist to understand the fundamentals of quantum computing. Below, we’ll introduce platforms, courses, books, and videos that can help you take your first steps.

1. Understand the Basics of Programming

First and foremost, it’s important to understand the basics of programming. While you don’t need to be an expert in physics, programming logic is key to navigating the world of quantum computing. If you already have experience in languages like Python, great! If not, learning to program is a good first step.

You can start with free courses like:

  • Python for Beginners Course (available on platforms like Codecademy or Coursera)
  • CS50 – Introduction to Computer Science (offered by Harvard University)

These courses will help you build a solid foundation in programming, which will be useful for programming quantum algorithms later on.

2. Quantum Computing Platforms for Beginners

There are several platforms that offer free quantum computing simulators and quantum cloud services, allowing you to start experimenting without needing advanced hardware.

  • IBM Quantum Experience: IBM offers an interactive platform where you can experiment with quantum circuits and simulate quantum algorithms. The platform features documentation, tutorials, and ready-made examples, ideal for beginners.
  • Microsoft Quantum Development Kit: Microsoft offers tools like Q#, a programming language designed for quantum computing, and Visual Studio to facilitate the development of quantum algorithms. There are many free tutorials to assist with learning.
  • Google Cirq: Google also has its own quantum computing platform called Cirq. It’s ideal for those with some programming experience who want to learn about quantum algorithms in an intuitive development environment.

These platforms are great for beginners since they don’t require physical hardware and allow you to develop your skills in a hands-on way.

3. Online Courses in Quantum Computing

There is a variety of online courses that teach quantum computing from scratch. Some of the best courses for beginners include:

  • Quantum Computing for Everyone – Coursera (taught by MIT): This course is an excellent introduction to the world of quantum computing. It introduces the basic concepts in an accessible way without requiring a background in physics. The course covers qubits, superposition, and entanglement.
  • Intro to Quantum Computing – Udemy: A simple and straightforward course focusing on understanding the fundamentals and how they can be applied to quantum programming.
  • Quantum Computing Fundamentals – edX (offered by University of Maryland): Provides a solid introduction to the concepts of quantum computing and how they apply to solving complex problems.

These courses are perfect for those who want to understand the theory behind quantum computing and learn how to program quantum algorithms on different platforms.

4. Introductory Books on Quantum Computing

Books are a great way to get a deeper understanding of the concepts. Here are some introductory books that are accessible and ideal for those without a physics background:

  • “Quantum Computation and Quantum Information” – Michael A. Nielsen and Isaac L. Chuang: This is one of the most recommended books for those looking to delve into quantum theory. While it is technical, it takes a detailed and accessible approach for beginners.
  • “Quantum Computing for Everyone” – Chris Bernhardt: This book provides an excellent introduction to quantum computing without relying on advanced physics concepts. It clearly and accessibly explains qubits, quantum gates, and algorithms.
  • “Dancing with Qubits: How quantum computing works and how it can change the world” – Robert S. Sutor: A more readable book aimed at readers without a technical background, perfect for those starting from scratch.

These books are perfect for supplementing your studies and gaining a broader view of how quantum computing can transform the world.

5. Educational Videos and Podcasts

If you’re more of a visual learner or prefer to learn by listening, videos and podcasts can be great resources to expand your knowledge of quantum computing. Some suggestions include:

  • YouTube – “Quantum Computing for the Determined”: This video series by Michael Nielsen offers a clear and fun way to explain the fundamentals of quantum computing.
  • Podcast “The Quantum Daily”: This podcast provides news, interviews, and explanations about quantum computing in a simple manner, ideal for beginners.
  • YouTube – “MinutePhysics”: This channel offers short, educational videos about physics and quantum computing, addressing concepts in a light and comprehensible way.

These videos and podcasts help you absorb key concepts in a more interactive and fun way.

6. Practice and Experimentation

Finally, the best way to learn quantum computing is by practicing. Experiment with quantum algorithms on platforms like IBM Quantum Experience and Google Cirq. Knowledge is consolidated by practicing, and quantum computing requires hands-on experience.

Over time, you’ll begin to better understand concepts like superposition, entanglement, and quantum algorithms.
