Helios reaches high-fidelity quantum performance

A new benchmark for trapped-ion systems

Fidelity measures how accurately a quantum computer performs an operation. This is essential because qubits are highly sensitive to disturbance. Even small errors can affect the outcome of a calculation, especially as systems become larger and computations become more complex.

Progress towards fault-tolerant computing

The Helios system was assessed with support from Sandia National Laboratories, using advanced benchmarking methods to evaluate its performance. The system also demonstrated mid-circuit measurement capabilities, which allow a quantum computer to check information during a computation.

This is an important requirement for quantum error correction. Fault-tolerant quantum computing depends on the ability to detect and correct errors while calculations are running, instead of only measuring the result at the end.

A step in a longer development process

Helios is not yet a fully fault-tolerant quantum computer. However, the results show continued progress in the hardware, control systems and benchmarking methods needed to get there.

For businesses following quantum technology, this type of milestone matters because reliability is one of the main conditions for future use. More qubits alone will not be enough. Quantum computers also need consistently accurate operations, stronger error correction and trusted ways to measure performance.

Helios shows that those building blocks are improving. Each gain in fidelity brings quantum computing closer to applications that require longer and more demanding calculations.
