Quantum error correction goes well beyond breakeven

Key points

• Quantinuum's latest quantum computing hardware, Helios, has demonstrated significant improvements in error correction. Each increase in the size of logical qubits improved performance by a factor of over 10, marking the best scaling seen yet.
• The company's advancements include reducing leakage errors by a factor of 6.5 and developing software to rapidly analyze error data.
• These developments bring quantum computing closer to practical applications, though challenges remain in scaling qubit counts and reducing hardware error rates.
