Summary

Sameh Yamany, CTO of VIAVI Solutions, presents at Q2B Tokyo 2026. He introduces VIAVI’s 100-year history in testing and optimization, highlighting their focus on photonics, wireless, security, sensing, and AI. The core of the talk is quantum-safe technology, addressing the threat of quantum computers to current encryption. He discusses two main approaches: Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC), advocating for a hybrid solution. VIAVI offers testing and validation services, including a ‘generative reality digital twin’ that replicates real network conditions to test quantum-safe systems. They are building a quantum-safe hub in Singapore and have a lab in Phoenix for 6G testing. He emphasizes the urgency of quantum-safe adoption due to ‘harvest now, decrypt later’ attacks and the long lifespan of data. He concludes by promoting VIAVI’s QST 1000 solution and encourages visiting their booth.

Critical Evaluation

Value of the Information & Strength of the Argument

The talk provides valuable insights into the practical challenges of implementing quantum-safe technologies, particularly the need for testing and validation. The argumentation is based on the speaker’s industry experience and positions VIAVI as a key enabler. However, it lacks concrete data, case studies, or comparative analysis, and the promotional tone limits its critical depth.

Scientific Rigor, Source Quality, Title Accuracy

The presentation is scientifically plausible but lacks rigorous sourcing. No specific studies or standards are cited, and claims about timelines (e.g., Q-Day) are presented without references. The title accurately reflects the content, but the talk is more of an industry update than a scientific exposition.
