Quantum Computer-Safe Cryptography Post-quantum cryptography refers to a subfield of cryptography that deals with cryptographic primitives that, unlike most asymmetric cryptosystems currently in use, are virtually impossible to decrypt even using quantum computers. With the help of quantum physics, robots learn faster and can therefore make a quick decision. This would be particularly helpful for autonomous driving and AI systems in cars. Qubit = Computing unit in Quantum Computers In quantum informatics, qubits form the basis for quantum computers and quantum cryptography. The qubit plays an analogous role to the classic bit on conventional computers: it serves as the smallest possible storage unit and at the same time defines a measure for quantum information. In industry, for example, the use of quantum sensors in mechanical and plant engineering as well as in the electrical, pharmaceutical and automotive industries is intended to make use of the technology. With the help of laser light, such sensors should be able to carry out measurements with a degree of precision that has so far either not been possible at all or only with immense effort and huge equipment.
