As a result, many government leaders are unfamiliar with quantum science or technology. So how can government leaders prepare for a somewhat unknown quantum future? The short answer is that pragmatic leaders can put in place the infrastructure to allow their organizations to capitalize on whatever developments quantum may bring, but this will have to be done at breakneck speed, with forethought and razor-sharp clarity, or this revolution will be dominated by others and the UK will just become a commodity user of other nation’s capabilities. This revolution and the pace of change was recently crystallised by Sundar Pichai, the CEO of Google, who said that a combination of artificial intelligence and quantum will ‘help us tackle some of the biggest problems we see’, but also said it was important encryption evolved to match this, stating that, ‘In a five-to-ten-year time frame, quantum computing will break encryption as we know it today.’
According to Dr Jonathan Dowling of Louisiana State University, current efforts to develop quantum computers are seeing the number of quantum bits on a quantum computer’s processor chips double every six months. “That is four times faster than Moore’s Law for classical chips, but the nature of quantum computers—[through] superposition and entanglement—means that their processing speed grows exponentially with the number of qubits. So, the processing power of quantum computers obeys double exponential growth,” Dowling noted. If this growth pattern continues, qubit processors could be capable of cracking one of the most widely used types of encryption, Rivest–Shamir–Adleman (RSA) encryption, and solving complex problems and simulations within the next decade.
In a recent report, Accenture stated that as a consequence of these performance increases in Quantum Computer development, there will be a ‘point at which a practical quantum computer will be able to break the security of our current encryption methods, and if by then our basic security infrastructure has not already shifted to a quantum-secure form, it will be too late. The time to look at options for a quantum-safe architecture is at a minimum 10 years ahead of the expected need date.’ Accenture go further, arguing that ‘Quantum Key Distribution provides a quantum-safe mechanism for key delivery that is independent of advances in cryptoanalysis and computing capabilities, whether classical or quantum and is thus not dependent on algorithmic security.’
In the Integrated Review, the government has initiated an additional investment of £1.4 billion more per year in core-funding for its world-leading research base, citing that this will, ‘enable institutions across the UK to push the frontiers of knowledge in areas ranging from quantum technologies for cryptography to new imaging technologies for cancer treatment.’ The level of investment is commendable, however, this funding has to cover the broadest range of future capabilities and technologies, without focus, it will be spread too thin, across to many areas and little change will result. In comparison, the US National Defense Authorization Act (NDAA), passed by both chambers of Congress in December, contained a provision that promises to increase government spending on quantum computing, AI and 5G technology by $10 billion annually over the next five years. A vast amount of money focussed on just two key initiatives.
So, what it is that we can do in the UK? It wants to be a meaningful Space nation but lacks the resource to truly make a difference and meet the unwritten ambition that really resides within Whitehall. In the 2010 Defence Review a strong argument was made for a Cyber Army – 12 years on it still does not exist and it is still way off in the future. In this IR
