Quantum computers: risks and opportunities for IT security at a glance!

Quantum computers: risks and opportunities for IT security at a glance!

On August 15, 2025 there were numerous exciting developments at TU Braunschweig and in the world of IT security. How TU Braunschweig reports, TU Braunschweig and Leibniz University Hannover are cooperating in the development of diamond-based lasers that offer up to four times higher frequency stability. This innovation could lead the way for the future of quantum computers, gravitational wave detectors and industrial applications.

A quantum escape game is also taking place in Paderborn in the Heinz Nixdorf MuseumsForum. This game allows users to explore the inner workings of a quantum computer in a fun way. The game is available for free on Steam and is a creative way to learn the complex concepts of quantum mechanics.

Important events and promotions

President Angela Ittel and Vice President Manfred Krafczyk made a special effort to spread a positive atmosphere during the exam period by distributing ice cream on the university square. A summer camp also took place at the TU Braunschweig in August, which gave 37 students the opportunity to conduct research in biology, physics and German under the guidance of students.

The networking event for university community builders in the Media Lab is on the agenda on August 21st. A keynote speech will be held here and best practices and networking opportunities will be offered. The 20th anniversary of the Braunschweig Green School will also be celebrated on the same day with a ceremony and an open summer festival. A brochure for the anniversary provides an overview of the activities of the last two decades.

Cyber ​​security in focus

In an increasingly connected world, cyber attacks are an everyday problem for companies. Loud iot-mesh.de 58 percent of German companies were affected by attacks last year. Looking at the future of IT security, Nils Gerhardt, CTO of Utimaco, identifies five key trends for 2024.

• Quantencomputer könnten herkömmliche Verschlüsselungen brechen, weshalb Unternehmen auf quantensichere Algorithmen umstellen sollten.
• Künstliche Intelligenz stellt eine Doppelherausforderung dar, da sie sowohl als Werkzeug für Cyberkriminelle genutzt werden kann, als auch Sicherheitsmaßnahmen verbessert.
• Nachhaltigkeit und Cyber-Sicherheit müssen Hand in Hand gehen, da Cyber-Angriffe erhebliche Verluste verursachen.
• Infrastrukturelle Resilienz ist entscheidend; Unternehmen sollten sichere eigene Infrastrukturen entwickeln, die externen Anbietern ergänzen.
• Der Fachkräftemangel in Cybersecurity gefährdet die Sicherheit; 68 Prozent der Unternehmen sind daher zusätzlichem Risiko ausgesetzt.

The dangers posed by quantum computers cannot be ignored. Security Insiders explains that cyber attackers are already storing encrypted data today in order to later decrypt it with quantum computers. Sensitive information in industry as well as diplomatic and military communications are particularly at risk.

The introduction of quantum computers will permanently change the cyber threat landscape. Experts recommend preparing now for the transition to post-quantum cryptographic processes in order to avoid systemic vulnerabilities. As the article further explains, blockchain technologies, for example, are vulnerable to breaches from quantum attacks.

In summary, it can be said that the developments at TU Braunschweig and the challenges in IT security represent central issues of our time. The combination of technological advances and the need for protective measures will be crucial in the coming years to both promote innovation and minimize risks.
