Error Correction and Noise: Current systems are in the "Noisy Intermediate-Scale Quantum" (NISQ) era, meaning they’re prone to errors due to environmental interference and imperfect gates. Progress in quantum error correction (QEC) is accelerating—Google demonstrated a surface code reducing errors in 2023, and startups like QuEra are exploring neutral-atom approaches. Still, full fault-tolerance (requiring thousands to millions of logical qubits) is years away.
