Understanding Quantum Computing
Quantum computing may seem a distant concept, often reserved for academia or high-tech labs. However, we must recognize that this perception is changing fast. The future of quantum technology is already unfolding, with actionable developments occurring in various sectors, including cybersecurity, high-efficiency data processing, and complex problem-solving.
At its core, quantum computing is fundamentally different. It processes information using quantum mechanics rather than classical binary logic, enabling it to solve certain problems much faster than traditional systems. This allows quantum computers to tackle particularly challenging problems much faster than their classical counterparts.
Imagine a powerful computer that can simulate complex chemical reactions or optimize logistics in ways that would take conventional computers years. As this technology matures, its applications will undoubtedly begin to impact daily business operations, forcing a rethink of traditional data management and security strategies.
Especially in the security field, the future release quantum requires a change in current security strategies to ensure the confidentiality and integrity of data in the years to come.
The Quantum momentum in the Netherlands
Close to home, we are witnessing significant progress in quantum technology through various initiatives, such as Quantum Delta NLi. Initiatives like this are forging strong ecosystems, connecting universities, startups, corporates, and government bodies.
One notable achievement from this collaboration is the quantum network in the Utrecht region. By using quantum, this network ensures that messages can be transmitted with integrity and confidentiality. Such measures are foundational in building trust in an increasingly interconnected digital world.
The cryptography challenge
Quantum computing’s rise brings cryptography into focus. Encryption underpins today’s digital security—from securing data and communications to verifying identity and ensuring transaction integrity. In our current landscape, robust cryptographic methods are essential for safeguarding sensitive data, ensuring transaction integrity, and preventing unauthorized access to systems.
Cryptography uses algorithms—basically, digital locks—to keep sensitive data safe. The longer and more complex the key, the harder it is to crack, even for the fastest traditional computers. This works well in most cases, but things get more complicated with asymmetric cryptography, which uses two different keys: one to lock (encrypt) and one to unlock (decrypt) the data.
Asymmetric cryptography has been reliable so far, but there's a growing concern: quantum computers. Experts believe that once these new types of computers reach full strength—known as “Q-day”—they could break the very fabric we depend on for secure communication and data protection. That moment hasn’t arrived yet, but it’s coming.
With over $55 billionii, invested globally in quantum technology, development is moving fast. That’s why business leaders should start thinking now about how quantum breakthroughs could impact their operations—and what steps they need to take to keep their data secure in the future.
Preparing for a post quantum future
With the digital world quickly changing, it’s smart for organizations to start looking at quantum-resistant cryptography. This new generation of cryptographic methods is engineered to withstand the power of quantum computing, posing challenges to even the most advanced quantum machines. The development of Post-Quantum Cryptography (PQC) algorithms offers a promising path forward, receiving ratification from important government bodies like NIST following rigorous validation.
This shift brings up some important questions organizations need to consider:
Are you aware of the location of sensitive information your organization handles?
Many companies likely possess data that must remain confidential for extended periods - think contracts, financial records, proprietary information, or personal data.
Where and which encryption methods does your organization currently use?
A thorough assessment is necessary to identify which systems nonchalantly rely on potentially vulnerable algorithms.
How long will it take to transition to updated, secure solutions?
While many businesses may hope for a quick turnaround, transitioning to new systems often requires considerable time and planning to ensure a smooth shift.
As we learn from past technological transformations like Y2K, it becomes evident that a proactive stance is a sound strategy for mitigating risks. Investments made in quantum-resistant cryptography today will pay dividends in maintaining security and business integrity in the future.
Lessons from past cybersecurity events
In light of recent high-profile cybersecurity breaches, we are reminded of the importance of remaining alert. Events like the Log4Jiii vulnerability and breaches involving digital certification companies like DigiNotariv highlight that the threat landscape continually evolves. The lessons learned from these events emphasize the importance of adapting security measures to mitigate emerging technologies and threats.
Organizations prioritizing cybersecurity and investing in preventive measures are better equipped to protect their sensitive data from new vulnerabilities. By taking proactive steps now to evaluate and enhance their security posture, organizations can maintain a competitive advantage and peace of mind.

Current threats of future quantum
One concept often arises in data security discussions: "Store now, decrypt later." This isn’t just science fiction. Some attackers—especially those backed by governments—might already be collecting encrypted data today, planning to unlock it later when quantum computers are powerful enough.
The danger isn’t imminent, but it’s unavoidable. Sensitive data sent today using traditional encryption could be compromised in a decade, or sooner. This creates a paradox: the very methods we rely on for security are the ones most at risk from tomorrow’s technology.
While we may have to accept this risk for now, it is vital that we remain forward-thinking. As the field of post-quantum cryptography (PQC) develops, it will soon provide commercial solutions that are resistant to the types of attacks posed by quantum computers. When these commercial solutions become available, it's crucial to transition to these more secure methods.
A call to action
The timeline may still be uncertain, but the need to act is not. Quantum computing is moving from theory to reality, and with that shift comes an opportunity to rethink how we protect sensitive data. Many organizations are starting to map their cryptographic landscape, explore quantum-resistant options, and connect with partners who can help guide the transition. These early steps not only build technical resilience but also create space for innovation and long-term confidence.
Quantum-Proof your organization
Quantum technology marks a significant shift in the digital landscape—one that invites thoughtful preparation rather than rushed reaction. Now is a good time to reflect on your current systems, start conversations within your teams, and explore what these developments might mean in your context. The pace of change will vary, but the need to adapt is clear. By taking steps today—however small—you contribute to building a more resilient, future-ready foundation.
