Its researchers have successfully demonstrated a novel approach that solves two major hurdles that have been limiting the scalability and commercial viability of quantum computers: the ‘wiring problem’ and the ‘sorting problem’.

Quantum computers hold immense potential to revolutionise various industries, from drug discovery to materials science. But achieving this potential hinges on the ability to build larger and more powerful quantum computers.

One of the most significant challenges in this pursuit is scalability – how to efficiently integrate and control a growing number of qubits (the quantum equivalent of bits in classical computers).

Quantinuum's researchers have developed a groundbreaking solution that addresses both the major problems. Traditionally, each qubit requires numerous control signals, making it impractical to scale to larger numbers.

Quantinuum's approach, detailed in a new scientific paper, utilises a clever combination of a fixed number of analog signals and a single digital input per qubit, significantly minimising the required control complexity. This method, coupled with a uniquely designed 2D trap chip, enables efficient qubit movement and interaction, overcoming the limitations of traditional linear or looped configurations.

This achievement directly addresses concerns regarding the scalability of Quantinuum's trapped-ion quantum computing architecture, proving its potential for future growth.

Dr Nash Palaniswamy, Chief Commercial Officer of Quantinuum, said: “This is a significant milestone not only for Quantinuum but for the entire quantum industry, propelling us into an era of widespread quantum commercialisation.

“Our team's groundbreaking work paves the way for building larger and more powerful quantum computers, enabling businesses to harness the transformative power of this technology and unlock real-world solutions across various sectors.”
