The global strategic landscape is being redrawn not on battlefields, but in the arcane realm of quantum physics. Microsoft’s unveiling last week of Majorana 1 is a technological bombshell: it is the first quantum chip powered by a topological core architecture, ensuring fault resistance.
This breakthrough demands an urgent rethinking of Australia’s move to post-quantum encryption, as it challenges the foundations of our defence and intelligence capabilities.
Quantum computing, with its unparalleled ability to solve problems that are intractable for even the most powerful classical computers, will revolutionise warfare. The potential to break encryption, develop new materials with unprecedented properties and accelerate artificial intelligence has the potential to negate existing strategic advantages and create new vulnerabilities.
The implications are stark and immediate for a nation, such as Australia, that relies heavily on secure communications, advanced materials and cutting-edge intelligence capabilities.
By harnessing the exotic properties of a new type of material called a topoconductor, Microsoft has been able with the Majorana 1 chip to create more reliable and scalable qubits, the fundamental building blocks of quantum computers.
This breakthrough has enabled the company to develop a quantum chip that is not only more stable but also more compact, paving the way for the development of quantum computers capable of tackling real-world problems.
To put this into perspective, the Majorana 1 chip can accommodate eight topological qubits on a chip designed to scale to one million. This is a staggering jump from existing high-end chips, which typically contain only a few dozen qubits. The ability to scale to a million qubits opens up the possibility of solving problems that are currently impossible for even the most powerful supercomputers.
Practical quantum computing has profound implications for Australia’s defence and security.
An advanced ability to break encryption could compromise sensitive government and military communications, as well as critical infrastructure, leaving us even more vulnerable to espionage and sabotage.
The development of new materials with enhanced properties could lead to the creation of advanced weapons systems and defensive technologies, potentially rendering current defence capabilities obsolete and upending the strategic balance.
The acceleration of artificial intelligence could have far-reaching consequences for intelligence gathering, decision-making and autonomous weapons systems, potentially outstripping Australia’s current capabilities and leaving us at a decisive disadvantage.
Advice from the Australian Signals Directorate, as outlined in Australia’s Information Security Manual, and Britain’s National Cyber Security Centre has encouraged the adoption of post-quantum encryption. However, this guidance has often been accompanied by the caveat that the development of cryptographically relevant quantum computers is likely still years away. Consequently, this advice is often framed as relevant for those looking to post-2030 security. The advancements from Microsoft suggest that this timeline may be much shorter than anticipated.
Australia must invest in research and development and devise strategies to mitigate the risks posed by quantum computing. As Microsoft technical fellow Matthias Troyer, says, ‘From the start, we wanted to make a quantum computer for commercial impact, not just thought leadership. We knew we needed a new qubit. We knew we had to scale.’
Australia needs a proactive and comprehensive approach to quantum computing, encompassing six key elements: accelerated research and development; cybersecurity resilience; strategic partnerships; workforce development; ethical frameworks; and rigorous self-regulation.
Increased investment in quantum computing research and development would ensure that Australia does not fall behind in the technology race. This investment should prioritise the development of quantum hardware and software, as well as the exploration of new applications and mitigation strategies.
Strengthening cybersecurity infrastructure and embracing global standards for quantum-resistant encryption algorithms would protect sensitive data and critical infrastructure from potential attacks. Australia must balance the use of global standards with investment in sovereign capabilities to avoid dependence on foreign technologies, which could be compromised or withheld in a conflict.
Collaboration with allies and partners, particularly the United States and Britain, would allow us to share knowledge, pool resources and develop a coordinated approach to face the challenges and seize the opportunities of quantum computing.
Investing in quantum education and workforce development would ensure that we have a skilled workforce capable of harnessing the potential of quantum. It would also help us to navigate the complexities of this new technology and maintain our competitive edge.
The development and deployment of quantum computing must be guided by robust ethical frameworks, ensuring that the technology is used for the benefit of humanity and does not exacerbate existing inequalities or create new risks.
Fostering a culture of responsible innovation and self-regulation within the quantum computing industry would maintain public trust and ensure ethical development and deployment of quantum capabilities.
Microsoft’s Majorana 1 chip is here and is real. The quantum revolution is not a distant prospect; it is unfolding before our eyes. Its implications for national security and our national well-being are profound and far-reaching. Australia needs to harness the transformative power of quantum computing while mitigating its risks. Our nation’s security, and indeed our place in the world, may depend on it.
