First look: Quantinuum's new Helios processor is a major engineering step for trapped-ion quantum computing, built to solve a problem that gets harder as systems grow: moving qubits through a machine without undermining their performance. The 98-qubit processor uses a four-way junction to route ions between memory and processing areas. It also relies on a control system that plans those movements while coordinating quantum operations. Together, the hardware and software give Helios more room to run operations in parallel than earlier trapped-ion designs.
Helios is the largest trapped-ion quantum computer demonstrated so far. Quantinuum, which is based in Cambridge, UK, and Broomfield, Colorado, previously demonstrated machines with 32 qubits in 2023 and 56 qubits in 2025.
The processoruses charged atoms, known as ions, as qubits. Electromagnetic fields hold the ions above the...
