Loading...Introduction to Quantum Error Correction
My team and I encountered a significant challenge last quarter when our quantum circuits started losing coherence at scale. We initially tried surface codes, but they didn't quite work out as planned. Here's what we learned from that experience and how we eventually found a solution that worked.
The Problem with Surface Codes
When I first tried implementing surface codes with IBM Qiskit, it broke because the error correction didn't account for the specific noise patterns in our hardware. The official docs didn't mention this crucial detail, so we had to figure it out the hard way. After 6 months of experimentation, we realized that surface codes, while powerful, aren't the best fit for our specific use case due to their high overhead in terms of qubits required for encoding.
Exploring Shor Codes
Given the limitations of surface codes, we decided to explore Shor codes as an alternative.
