Quantum Information Processing is usually taught as an elective in the master's degree in physics. We argue that a basic understanding of Quantum Information Processing can already be achieved by high school juniors and seniors. Moreover, we explain why it is useful to teach Quantum Information at this level and describe a teaching unit which has already been tested in the classroom. We will hereby focus on didactical reductions and describe some physical basics.

The tutorial will review the field of quantum information processing, i.e. quantum cryptography, quantum error correction codes, quantum computing..., starting from basic ideas, to the present state-of-the-art. We will also identify some critical technologies as well as discuss the potential impact on communications.

We describe some instances in quantum information processing where numerical range techniques arise. We focus on two basic settings: higher-rank numerical ranges and their relevance in theoretical quantum error correction, and the classical numerical range and its use for comparing quantum information processing operations. We present the basic theory, discuss examples and formulate open problems.
