Quokka: the little device set to democratize quantum computing

In our most recent episode of Lexicon, we sat down with Chris Ferrie , an associate professor at the University of Technology Sydney and a popular science author. Chris also happens to be one-half of the founding members of Eigen Systems .

We discussed his company’s Quokka quantum computer emulator, which aims to democratize quantum computing education. Let’s find out how.

The team behind the Quokka

Chris Ferrie has made it his mission to make quantum computing accessible to a broader audience. Ferrie’s background is both diverse and impressive.

He is deeply involved in academic research at the Centre for Quantum Software and Information. He has authored several books on quantum physics for various age groups, including the best-selling “Quantum Physics for Babies.”

What is the Quokka?

The Quokka, named after a photogenic Australian marsupial, is crucial to this mission. Regarding the choice of name, Ferrie explained to IE , “If you have a quantum product or a company, it has to start with Q or have a Q. And there’s only one native animal in Australia with a Q. So we went with Quokka.”

But beyond the interesting name lies a serious piece of kit designed to bridge the gap between abstract quantum theory and practical application. Under the hood, the Quokka is a quantum computer emulator that simulates a 30-qubit fault-tolerant quantum computer.

Chris explained that the Quokka can mimic the behavior of a highly reliable quantum computer that currently does not exist. It provides users with a platform to experiment with quantum algorithms and programs. Unlike other quantum simulators that run on cloud-based systems, the Quokka is a physical device that fits in the palm of your hand. This makes the experience of interacting with quantum computing tangible and immediate.

“The most important thing I’ve discovered is that student engagement spikes when tasked with building things rather than just being force-fed formulas and jargon,” Chris explained.

The Quokka embodies this philosophy by allowing users to write and run quantum assembly programs on the device, providing real-time feedback and results. This approach not only makes quantum computing more engaging but also demystifies a field that is often seen as inaccessible.

Ferrie explained to IE , “One of the most important things about the emulator is it acts like a black box, which is exactly how a quantum computer will act. You can’t watch a quantum computation happen.”

Why it matters

But, as Ferrie pointed out, the Quokka is more than just a teaching tool. It represents a significant step toward making quantum computing a part of everyday education and literacy.

Traditional teaching methods make this concept difficult to grasp. The Quokka is more than just a teaching tool; it represents a significant step toward making quantum computing a part of everyday education and literacy.

And it is important to get to grips with this technology early as quantum computers are poised to revolutionize industries. This will likely include fields like cryptography, drug discovery, materials science, and financial modeling by solving problems that are currently beyond the capabilities of classical computers

As Chris highlighted, quantum literacy has been recognized as a priority in educational strategies worldwide. However, as Ferrie noted, “The approaches that have been taken so far haven’t stuck. Again, it’s about sustainability.”

Many quantum education initiatives have been short-lived, relying on goodwill rather than sustainable models. The Quokka aims to change this by providing a durable, scalable platform for quantum education that can be integrated into existing STEM curricula.

Quantum computing for the masses

Ferrie also highlighted the potential for the Quokka to serve as a gateway to deeper engagement with quantum computing.

“You can use quantum computing in Quokka to teach components of existing curricula across all of STEM, even if they don’t mention quantum. And believe me, they won’t mention quantum for at least 20 years,” Ferrie explained.

By incorporating quantum concepts into broader STEM education, Quokka helps prepare students for a future in which quantum computing is a fundamental part of the technological landscape. Another critical aspect of the Quokka is its potential to inspire innovation.

Ferrie compared the device to early personal computers, which empowered a generation of hobbyists and hackers to explore new ideas and create groundbreaking technologies.

“We want to give it to the young innovators, hackers, hobbyists, and students to come up with something that we could never think of,” Ferrie said. By making quantum computing more accessible, the Quokka could help cultivate the next generation of quantum innovators.

Looking ahead

While the Quokka is already making waves in the quantum education community, Ferrie and his team at Eigen Systems have even more ambitious plans for the future. For example, they actively seek partnerships with educational institutions, government organizations, and philanthropists to make the device accessible to underfunded schools and communities.

“We would love to make it accessible to underfunded schools and communities that can’t afford an expensive piece of kit,” Ferrie explained, highlighting the team’s commitment to broadening access to quantum education.

As Chris explained, the Quokka is available for $395 . He feels this reflects the cost of small production runs and the startup’s bootstrapping nature.

However, Ferrie is optimistic that as the project scales, costs will decrease, making the device more affordable for a wider audience. In addition to the hardware, Eigen Systems is developing a range of educational content and programming interfaces to support users of all levels.
