Is an optical computer the best DIY idea of a quantum computer?

Well, I personally love the idea of quantum computing but couldn't find a practical use of them in my personal projects or even my business. But I love to understand how they work. I searched the internet and found that there are tons of demonstrations on YouTube which are using lasers to give you the idea of a quantum computer. So I did a deeper search and found out those are basically simple optical computers. The main question here is, isn't the main concept of "optical computer" replacing electrons with photons? So they can be normal computers and quantum ones as well. Since there are a lot of ways to make a normal computer, I just got curious about the most DIY approach to build a quantum one, obviously for learning about "under the hood" procedures. Otherwise I don't have a few million dollars to spend on a super cold room holding a chip which I don't know what it's good for and if I want to work with real life quantum computers, there are a good bunch of companies offering their services. submitted by /u/Haghiri75 [link] [comments]
