April 14 – World Quantum Day

1 min

April 14 marks World Quantum Day, an annual international initiative that highlights the importance of quantum physics and rapidly developing quantum technologies. The date was not chosen at random—the number 14.4 symbolically refers to Planck’s constant (4.14 × 10⁻¹⁵ eV·s), one of the fundamental pillars of modern physics.

World Quantum Day was established in 2022 with the aim of making quantum topics more accessible to both the professional and general public. Today, it is no longer just about theory—quantum principles underpin technologies that will significantly influence the fields of IT, communications, data processing, and cybersecurity in the coming years.

Security is one of the areas where the implications of quantum technologies are already being addressed today. Quantum computers could fundamentally change the way encryption works in the future, which is why post-quantum security is becoming an increasingly common topic not only for large organizations but also for ordinary businesses.

Are you wondering how to prepare for the post-quantum era today? At ITS, we help companies navigate new security threats and technologies and propose concrete steps to protect their data and communications. Get in touch with us and together we’ll discuss how you can increase the resilience of your IT environment for the future.
