Introduction to Quantum Information Technologies

The programme is intended for professionals from the IT and cybersecurity sectors, public administration, research institutions, and academia who seek a practical and comprehensible introduction to quantum technologies and their implementation in modern communication infrastructures. The course combines theoretical foundations with practical demonstrations and laboratory exercises focused on quantum communication, quantum-safe cryptography, and the integration of quantum technologies into existing network infrastructures. Course Structure Module 1: Introduction to Quantum Technologies (5 hours) Introduction to quantum information technologies and the fundamental principles of quantum systems. Participants will become familiar with essential concepts and technologies, including qubits, quantum measurement, superposition, entanglement, and quantum channels. The module also introduces practical applications and current technological capabilities. The course further provides an overview of major application domains, particularly quantum communication, Quantum Key Distribution (QKD), and the EuroQCI initiative aimed at building secure European quantum communication infrastructure with extremely high levels of security. Module 2: Optical Quantum Cryptography in Practice (5 hours) This module introduces optical quantum cryptography as a practical application of quantum communication technologies. Special emphasis is placed on the principles of Quantum Key Distribution (QKD), including shared key generation, quantum measurement principles, and eavesdropping detection mechanisms. During the practical sessions, participants will become familiar with the main QKD approaches and protocols, including BB84, E91, and CV-QKD. The module also discusses the key advantages and practical limitations of real-world QKD deployment. Module 3: QKD for Optical Fibre Networks and Communication Infrastructure (5 hours) This module focuses on the integration of quantum technologies into modern communication infrastructures in compliance with ITU and ETSI standards. Participants will explore the deployment of QKD within IP networks and hybrid communication environments. The practical part includes laboratory work with real QKD devices, their configuration, troubleshooting, and integration into network infrastructure. Participants will also assemble and test communication infrastructure within the CTU quantum communication testbed. For decision-makers and management-level participants, part of the seminar will address legislative, operational, and investment-related aspects of QKD deployment. Module 4: Fundamentals of Post-Quantum Cryptography (5 hours) Participants will gain an overview of classical cryptography and understand its critical vulnerabilities in relation to emerging quantum algorithms. The module explains the principles of Post-Quantum Cryptography (PQC) and clarifies the differences between PQC and QKD. Participants will become familiar with quantum-resistant cryptographic constructions, particularly standardized digital signature mechanisms and lattice-based key establishment schemes. The course also discusses the advantages and disadvantages of software-based quantum-resistant solutions (PQC) compared to QKD technologies.

After successful completion of the programme, participants will be able to: Understand strategic and technological developments in quantum technologies, including expected future trends and European Commission initiatives related to quantum security. Explain the principles, benefits, and limitations of quantum communication technologies, particularly Quantum Key Distribution (QKD), including practical implementation methods and deployment constraints. Implement QKD technologies within modern communication infrastructures while respecting relevant ITU and ETSI standards. Identify vulnerabilities of classical cryptographic systems in the context of quantum computing threats and explain the necessity of transitioning toward quantum-resistant security solutions. Understand the principles and practical applications of Post-Quantum Cryptography (PQC), including currently available software libraries and quantum-resistant cryptographic mechanisms.
