A new report looks at the state of post-quantum cryptography (PQC) from the perspective of
cybersecurity professionals, finding that 48 percent of organizations aren’t prepared to confront the urgent challenges posed by quantum computing.

The report from Keyfactor, based on a survey of 450 cybersecurity leaders across North America and Europe carried out by Wakefield Research, finds mid-sized organizations are particularly vulnerable, with 56 percent saying they are not ready.

Quantum computing is something that we've been covering for a while but commercial implementations always seem to be tantalizingly out of reach.

It could be getting nearer though thanks to work by Classiq Technologies, with Deloitte Tohmatsu Group, and Mitsubishi Chemical Corporation to demonstrate improved circuit compression.

Our world is gripped by uncertainty. From economic volatility to the climate crisis, businesses and individuals alike are navigating a landscape marred by unpredictability. As the World Economic Forum warns in its most recent global risk report, our outdated digital infrastructure and subsequent services are struggling to keep pace with the growing demands of the modern world.

As emerging technologies like AI, Blockchain and even 5G hit everyday life like a tidal wave, we need something that can not only help us navigate our way but also handle the waves. Think of it like trying to cross an ocean on a rowboat, without a compass. What we need is a modern cruise ship.

Now that we're beginning to overcome the obstacles to creating a commercially viable quantum computer it's important to consider the security threat that these vastly more powerful machines will pose.

Not least of these is the threat to encryption which puts everyone's online security at risk. We spoke to Nils Gerhardt, chief technology officer and head of product for Utimaco, to explore what a post-quantum future may look like.

The race to successfully build quantum computers is on. With the potential to solve all manner of problems for humanity, players across the globe -- from tech companies to academic institutions to governments -- have been busy investing significant resources into quantum computing initiatives for some years now.

But what are they exactly? A traditional (digital) computer processes zeros and ones, so called bits. These, to a first order approximation, are represented as on/off electrical signals. Quantum computers, on the other hand, leverage quantum mechanics to process information using quantum-bits or qubits, which can represent multiple states simultaneously. And it’s this capability that enables quantum computers to tackle computational tasks that are currently out of the question for classical computers - think factoring large numbers, simulating quantum systems, optimizing complex systems or solving certain types of optimization and machine learning problems.

As widely available quantum computing draws closer, organizations need to consider the extent to which their supply chain presents risks and start building in post quantum readiness to their risk assessments.

To do this, it's critical for businesses to understand the origin and authenticity of all the components that are in the supply chain (both hardware and software). This is especially true for IoT devices, which rely on systems and subsystems created by multiple partners and vendors bringing their solutions together to make a fully functioning connected product/system.

One of the biggest challenges of digital technology today is around security systems and data. In response to this, sophisticated algorithms have been designed to encrypt data and protect it through frameworks known as symmetric cryptography. While this has proven successful, advancements in quantum computing -- which utilizes quantum mechanics to solve complex problems faster than conventional computers -- could potentially turn data security on its head.

IBM, Microsoft and Google have already turned their attention to quantum computing and, as a result, commercially viable quantum computers are not too far from becoming a reality. In fact the global quantum computing market size in terms of revenue was estimated to be USD 866 Million in 2023 and is poised to reach USD 4,375 Million by 2028, growing at a CAGR of 38.3 percent from 2023 to 2028. This is raising concerns that these computers might pose a threat to current public-key cryptography algorithms and potentially expose sensitive data. As such, data security needs to be a step ahead, with more advanced cryptographic algorithms that minimise potential risks and ensure the safeguarding of data in a quantum computing world.

Cybersecurity company Thales is launching a first-of-its-kind Post Quantum Cryptography (PQC) Starter Kit in collaboration with Quantinuum, aimed at supporting enterprises in their transition to a post-quantum era and helping them understand the implications that quantum computing will have on the security of their infrastructure.

While 73 percent of organizations recognize quantum computing poses a threat to traditional cryptography, 61 percent have yet to define a strategy for a post-quantum world.

One of the key recent concerns for security teams has been developing the ability to adapt to advancements in technology and innovations such as AI and quantum computing.

A new partnership between Accenture and SandboxAQ aims to give organizations the ability to scan all of their files, applications and network traffic to ensure that all of their data -- whether on-premise or hosted via major cloud providers -- is secure even if attackers break through firewalls and network endpoints.

The classical computer has been the bedrock of computing for over 50 years. That’s going to change soon. quantum computing, which was once a concept limited to fringe scientific papers, is now becoming a mainstream topic.

We’re seeing significant breakthroughs in the headlines which are stoking the flames of conjecture. The truth is, that this technology will bring with it much more than hype and opportunities to breathe life into sci-fi creations. In this article, we’re going to dive into some of the milestones of quantum computing, future goals and, of course, the challenges that we still have to overcome.
