Quantinuum Reports 99.9995% Logical Memory Fidelity on Helios

Quantinuum achieved a logical memory fidelity of 99.9995% per error-correction cycle on its Helios trapped-ion quantum computer, significantly improving quantum information stability. This milestone supports the development of their Apollo universal fault-tolerant quantum system planned for 2029 and demonstrates the role of neural networks in real-time quantum error decoding.
