The first real breakthroughs in quantum computing occurred in 2019. Calculations which are not based on classical physics, i.e. on or off, but on the basis of quantum mechanical states theoretically allow many parallel calculations. On the other hand, our current security in networks is based on the assumption that the decryption of data or data streams does not take place within a few seconds or minutes, but rather would take many centuries. Quantum Computing would destroy all encryption and security that we know today. What does this mean for cybersecurity?
