Cobalt honeycombs open a new path to quantum computing

Cobalt honeycombs open a new path to quantum computing

Honeycombs are famous for their elegant design, but now they may have found a new application: quantum computing. To collect knowledge from subatomic particles, quantum computers require carefully designed materials capable of performing necessary, complex functions. However, the metals used, such as ruthenium and iridium, are often rare and expensive, limiting the potential to build new technology.

Why this matters
Why now

Researchers are continuously exploring new materials to overcome the limitations of current quantum computing technologies, specifically the high cost and rarity of traditional materials like ruthenium and iridium.

Why it’s important

This breakthrough offers a potential pathway to more scalable and cost-effective quantum computer construction by utilizing a more abundant element, which could accelerate the development and deployment of quantum technology.
