Quantinuum Unveils 98-Qubit Helios With 0.079% Two-Qubit Error Rate
3 articles · Updated · The Conversation · Jun 24
Summary
Quantinuum’s new Helios processor combines 98 trapped-ion qubits with all-to-all connectivity, a design aimed at scaling quantum systems without sacrificing control.
Nature data put Helios’ average single-qubit gate error at about 2.5 in 100,000 and two-qubit gate error at 7.9 in 10,000, near the best reported levels for harder two-qubit operations.
The machine uses a QCCD architecture with barium ions moved between storage and operation zones, plus software that routes ions and adjusts control decisions while programs are running.
Helios also ran random quantum circuits that are extremely hard to simulate classically, though that benchmark stops short of proving broad practical utility in fields like chemistry or engineering.
The advance matters because quantum progress depends less on raw qubit counts than on how many high-quality qubits can execute long, low-error calculations; Quantinuum’s previous largest system had 56 qubits.
Is the true innovation in Helios its powerful hardware, or the advanced software that finally makes it a programmable computing system?
Is Helios's trapped-ion architecture the winning design, or will competing technologies from rivals like IBM and Google ultimately prove more scalable?
After a $1.68B IPO, what is Quantinuum's realistic roadmap to profitability beyond selling access to researchers for experimental use?
