Anna Beata Kalisz Hedegaard

Anna Beata Kalisz Hedegaard

Course Presenter

Physicist with dual Master of Science degrees from Wright State University (Electrical Engineering) and University of Southern Denmark (Theoretical Cosmology). CEO and Founder of Quantum Prime. Over 15 years of international experience in deep-tech, telecommunications, and defence communications networks across six countries.

What You Will Learn

Six structured modules covering the complete landscape of quantum cybersecurity. Each module includes video lectures, key takeaways, and review questions.

1

Introduction to Quantum Computing

  • What is quantum computing and why it matters now
  • Qubits, superposition, and entanglement explained without jargon
  • Current state of quantum hardware and realistic timelines
2

Quantum Threats to Cybersecurity

  • How quantum computers break RSA, ECC, and other public-key algorithms
  • Harvest Now, Decrypt Later: the threat that already exists
  • Timelines for cryptographic risk: what the research actually says
3

Post-Quantum Cryptography (PQC)

  • NIST PQC standardisation process and selected algorithms
  • Lattice-based, code-based, and hash-based approaches
  • Migration planning: where to start and what to prioritise
4

Quantum Key Distribution (QKD)

  • How QKD works: BB84 protocol and photon-based key exchange
  • QKD vs PQC: complementary approaches, not competing ones
  • Current deployment examples in defence and telecommunications
5

Quantum Random Number Generation

  • Why true randomness matters for cryptographic security
  • How quantum random number generators work
  • QRNG certification standards and integration pathways
6

Building a Quantum Security Roadmap

  • Assessing your organisation's quantum risk exposure
  • Creating a phased migration plan aligned to business priorities
  • Governance frameworks and board-level reporting on quantum readiness

Certification

On passing the examination you receive:

  • A signed PDF certificate suitable for high-quality printing and framing
  • A LinkedIn digital badge to display on your professional profile
  • Certification in "Introduction to Quantum Cyber Security" issued by QSECDEF

Exam format: Multiple-choice

Passing grade: 80%

Study time: Approximately 4-5 hours of video lectures

Prerequisites: None. No previous technical experience is required.
