Milestone Needed To Be Achieved In Quantum Computing With Error Correction Apr 2026

Once a single logical qubit outperforms its physical parts, researchers must prove they can scale the "distance" of the code. In QEC, "distance" refers to the number of physical qubits used to protect a single logical state; a higher distance can correct more simultaneous errors.

: Error correction itself requires additional gates and measurements, which can introduce more errors. Once a single logical qubit outperforms its physical

: Without this scalability, we cannot drive logical error rates down to the 10-810 to the negative 8 power 10-1210 to the negative 12 power levels required for useful commercial algorithms. 3.
