AI summary

What happened, with direct paths to the underlying reporting

Quantinuum reported a world-record error-correction result on its Helios computer with 99.9995% logical fidelity (five errors per million). The color-code approach uses up to 37 physical qubits per logical qubit, delivering a tenfold improvement versus September and placing Apollo’s 2029 fault-tolerant objective within reach, prompting a rally in QNT to about $38.50.

  • QNT jumps on Helios breakthrough; fidelity hits 99.9995%.
  • Error rate: five per million; 10x improvement from September.
  • Color code uses up to 37 physical qubits per logical qubit.
  • Apollo 2029 fault-tolerant target brought closer; QNT rises ~5%.
