Preparation for the Certified Quantum Network Engineer Exam
Telecom operators now sell commercial quantum network services, beyond research demonstrations. QKD networks are operational in multiple countries. Entanglement distribution over metropolitan and intercity distances has been demonstrated. Standards bodies are developing interoperability frameworks. To evaluate these developments, network engineers and security professionals need to understand the technology in more depth than marketing materials provide.
CQNE training provides that depth. The curriculum covers QKD protocols, quantum network architectures, hardware components, and classical-quantum network integration. It also covers security analysis, including implementation vulnerabilities that theoretical security proofs do not address. The last module covers where QKD is actually deployed.
Course Outline
Module 1 Quantum Networking Fundamentals
The physical principles: photon polarization, entanglement, the no-cloning theorem, and why these properties enable secure key distribution. What makes quantum networking fundamentally different from classical secure communications. The distinction between QKD (exchanging cryptographic keys) and full quantum networking (distributing entanglement for computation and communication). Where quantum networking fits alongside PQC in secure communications.
Module 2 QKD Protocols
BB84 and its variants: how the protocol works step by step, parameter estimation, privacy amplification, and key rate calculation. Decoy-state protocols and why they are essential for practical implementations. Measurement-device-independent (MDI) QKD: removing detector vulnerabilities. Twin-field QKD: extending range beyond the direct transmission limit. Continuous-variable QKD: an alternative approach using standard telecom components. Protocol comparison: security properties, key rates, distance limits, and hardware requirements.
Module 3 Quantum Network Architectures
Point-to-point QKD links: the simplest deployment model, range limitations, and where it is sufficient. Trusted-node networks: extending range through intermediate nodes that are physically secured, the trust model and its limitations. Entanglement-based networks: the long-term vision for quantum networking, quantum repeaters, quantum memories, and current technology readiness. Satellite QKD: overcoming terrestrial range limits through free-space optical links. Metro networks versus long-haul connections. Network topology design for different security requirements.
Module 4 Hardware Evaluation
Evaluating the components that make up a QKD system. Single-photon sources: attenuated lasers versus true single-photon emitters, the performance implications. Single-photon detectors: avalanche photodiodes versus superconducting nanowire detectors, dark counts, timing jitter, detection efficiency. Quantum random number generators: why quality randomness is critical and how to evaluate generators. Optical components: fiber, free-space links, wavelength considerations. System-level evaluation: key rate, maximum distance, form factor, power requirements, and integration interfaces.
Module 5 Security Analysis
The gap between theoretical security proofs and practical security. Side-channel attacks against real QKD implementations: photon-number splitting attacks, detector blinding attacks, Trojan-horse attacks. How these attacks work, how they are detected, and what countermeasures exist. The role of certification and testing standards (ETSI QKD, Common Criteria). Security analysis methodology: how to assess the actual security of a QKD implementation, beyond the theoretical proof.
Module 6 Classical-Quantum Integration
QKD systems work alongside classical networking infrastructure and do not replace it. Key management: how quantum-derived keys are handed off to classical encryption systems, key lifecycle management, and key storage requirements. Network management: monitoring QKD link health, managing key inventories, handling link failures and rerouting. Integration with existing security architectures: how QKD-derived keys feed into IPsec, MACsec, or application-layer encryption. Operational considerations: installation, maintenance, and troubleshooting.
Module 7 Where QKD Is Actually Deployed
Operational QKD networks: China’s Beijing-Shanghai backbone, European initiatives (EuroQCI, UK Quantum Network), commercial deployments in Singapore, South Korea, and Japan. Standards development: ETSI ISG QKD, ITU-T SG13 and SG17, ISO/IEC. Government programs and funding. Vendors: established players and emerging companies. Market maturity assessment: where quantum networking is production-ready versus still developmental.
Format and Delivery
This program is available online on-demand, live online, in person, and as private team training. Current prices for each format are in the booking section below. Live online and in-person sessions include 180 days of access to the online on-demand course. Where that course is not yet published, the 180 days start on the day it is. However you train, every exam is a proctored assessment. We confirm the arrangements when you book.
Live online and in-person training runs over four days, with 24 hours of instruction in total. Each day has six hours of teaching within a seven-and-a-half-hour schedule that includes lunch and breaks. The online on-demand course covers the same material and takes roughly 40 hours at your own pace.
Prerequisites
None. No quantum physics background is needed. The course starts from the fundamentals.

Who this course is for
Network engineers, security engineers, telecom professionals, government and defense technology specialists, and technical evaluators responsible for assessing or deploying quantum networking.
What you’ll be able to do afterward
- Explain QKD protocols (BB84, E91, MDI-QKD, decoy-state) and their security properties
- Evaluate quantum network architectures (point-to-point, trusted-node, entanglement-based)
- Assess quantum networking hardware (single-photon detectors, sources, QRNGs)
- Analyze QKD security including implementation vulnerabilities and side-channel risks
- Design classical-quantum network integration approaches
- Evaluate global quantum networking deployments and vendor offerings
What you leave with
When you finish, we email you the course handbook, a PDF of every slide with notes that explain it in full. We also include a PDF copy of Quantum Systems Integration. The handbook is yours to keep.
Enrollment includes 180 days of access to the online on-demand course. Where that course is not yet published, the 180 days start on the day it is.
Where this course fits
Nothing is required. Introduction to Quantum Computing or Quantum Computing Fundamentals both help if the physics is unfamiliar. CQNA Network Architect Training is the design-level step up. Quantum Networking and QKD Essentials fills any gaps in the underlying physics.
Why we teach this
The material is based on Quantum Systems Integration, the reference text on quantum computing, networking, and sensing written by the course author. It also draws on faculty who work with quantum engineering and integration teams. We teach what we have had to get right in the field. We focus on the judgment calls you will face in practice, and vendor roadmaps are not part of the course.
Certificate of Completion
Upon completion, you receive a Quantum Academy certificate of completion. It is separate from our professional certifications and states your CPE credits, one for each 60 minutes of teaching. ISC2 counts them as professional development, and other certifying bodies set their own rules. The credits also count toward renewing a Quantum Academy certification. Our CPE credits page explains how to claim them.
About this program
Quantum Academy credentials are private professional credentials issued by Quantum Academy, a trade name of Post-Quantum Institute. They are not government-issued licenses, accredited degrees, or academic credit, and earning one does not guarantee employment, promotion, regulatory approval, or any other specific outcome.
Quantum Academy programs are educational and informational only, and are not legal, compliance, or engineering advice.
