#556: Stop HARVEST Now DECRYPT Later Attacks: Survive Post Quantum Attacks

Quantum computing isn’t just 10 years away, it’s happening now. In this deep dive, I sit down with Ramana Kompella, Head of Research at Cisco Outshift, to separate the sci-fi vaporware from the engineering reality.

We discuss the immediate threat of "Harvest Now, Decrypt Later" attacks, where bad actors steal your encrypted data today to unlock it with quantum computers tomorrow. Ramana breaks down exactly how Cisco is building the "Quantum Network" to counter this, leveraging the "No Cloning Theorem" to create unhackable communication channels.

If you are in cybersecurity, networking, or studying computer science, this is your roadmap to the future. We cover the math you need to learn (Linear Algebra), the timeline for real-world adoption (it’s closer than you think), and how Quantum Teleportation actually works at a packet level.

Topics Covered:

• The 5-Year Timeline: Why the "decade away" myth is wrong.

• Quantum Networking vs. Computing: Why we need to interconnect

quantum processors.

• The Physics of Security: How Entanglement and Teleportation prevent

eavesdropping.

• Career Advice: Why Linear Algebra is the most critical skill for AI and

Quantum jobs.

• Cisco x IBM: The partnership building the future internet.

Big thanks to Cisco for sponsoring this video and sponsoring my trip to Cisco Live Amsterdam 2026.
