Quantum Communication

Quantum technology is the next big leap innovation in many technical fields. In addition to quantum computers, quantum sensors and quantum imaging, developments are focusing primarily on quantum communication and quantum encryption for secure and private data communication. Here, classical encryption approaches based on computational complexity will be replaced by novel quantum key distribution approaches in combination with post-quantum cryptography. This type of encryption cannot be cracked even with arbitrary time and computational power.

Since existing cryptography is already threatened in the near future by the ever-increasing computational power of quantum computers, solution approaches must be developed in time to prevent an insecure transition period. Fraunhofer IPMS is engaged in research on this with its partners.
