Exciting to see the interest in quantum computing! I hope this guide helps clarify some concepts and benefits.

I've been following the developments in quantum computing for years, but I still can't figure out how it's fundamentally different from classical computing. Can someone explain?

Classical computing relies on bits that are either 0s or 1s, while quantum computers use quantum bits or qubits that can be in various states, including 0, 1, and a superposition of both. This allows quantum computers to perform certain calculations much faster than classical computers. I believe this guide starts with fundamental concepts and covers more advanced ideas, so it could be a helpful resource depending on your prior knowledge and willingness to learn.

One way to think of qubits is as a spherical dice with many sides that can represent a variety of states between 0 and 1, unlike the traditional six-sided dice. In this context, qubits can have infinite outcomes unlike classical bits which are limited to two. Other fundamental concepts include quantum entanglement and quantum tunneling.

I just started reading about quantum computing a week ago. Would this guide be useful to me, or is it too advanced?

Even if you have just started learning, this guide could help your understanding of quantum computing by introducing basics such as qubits, quantum gates, superposition, and entanglement. Later parts cover error correction, potential use cases, and existing quantum technologies. But be aware, the underlying concepts and math can often be challenging. Happy learning! :)

I've heard that quantum computing will completely change the way we approach many computing challenges. How long do you think before it's widely adopted in industries such as banking, finance, chemistry, etc.?

I agree with the excitement around quantum, but it will be a while before widespread quantum computing becomes a reality due to various challenges, including noise and errors in quantum operations, a lack of practical optimization techniques for large-scale algorithms, and unscalable hardware implementation. Solving these issues could take five to ten years, if not more. That said, some early applications, such as in security/cryptography, are emerging now.

I have always wondered if quantum computing would be useful in gaming. Could it lead to more realistic physics simulations, or faster AI bots generation?

There are already some quantum algorithms that can increase speed for specific types of calculations that could be useful in the gaming industry. For example, one day, it might allow for more intricate real-time strategy games with more complicated AI agents due to their ability to quickly search through exponentially large state spaces. While it's still experimental, some developers have toyed with the ideas that might emerge from dedicated quantum game engines.
