Quantum navigation: Unhackable, GPS-free

What happens when GPS goes down: jammed, spoofed, or completely denied? In this episode of TechFirst, host John Koetsier sits down with Michael Biercuk, founder and CEO of Q-CTRL, to explore one of the most surprising breakthroughs in quantum technology: quantum navigation. While most of the quantum world is focused on computing, Q-CTRL is building something entirely different: AI-powered quantum sensing systems that can navigate aircraft, drones, and vehicles without GPS. Even more surprising? This technology didn’t exist just over a year ago. Now it’s already shipping. You’ll learn: • How quantum sensors can “see” invisible features of the Earth • Why magnetic and gravitational fields enable GPS-free navigation • How this system achieves 100x better accuracy than current GPS alternatives • Why it works in environments where other systems fail (clouds, water, darkness, interference) • The role of AI software in stabilizing fragile quantum systems in real-world conditions • What this means for aviation, defense, and the future of autonomous systems This is a deep dive into a fast-moving frontier where quantum meets real-world deployment, and it’s happening faster than almost anyone expected. ⸻ Guest: • Michael Biercuk, Founder & CEO, Q-CTRL • Company: Q-CTRL • Website: https://q-ctrl.com ⸻ 👉 Subscribe for more conversations on AI, quantum tech, and the future of innovation: https://techfirst.substack.com ⸻ ⏱️ Chapters 0:00 Quantum Navigation vs Quantum Computing 0:34 Introduction to Michael Biercuk & Q-CTRL 1:12 What Is Quantum Navigation? 2:00 How Quantum Sensors Enable Navigation 2:52 Magnetometers vs Gravimeters Explained 3:28 Do You Need to Pre-Map the Earth? 4:18 Earth’s Magnetic Field & Why Maps Stay Accurate 5:18 GPS Spoofing & Why Quantum Nav Matters 6:00 Accuracy: 100x Better Than GPS Alternatives 7:00 Why Multi-Mode Navigation Is the Future 7:42 Limits of Star Cameras & Visual Navigation 8:38 The Vibration Problem in Quantum Systems 9:30 How Software Replaces Hardware Stabilization 10:28 System Size: From Sensor to Loaf of Bread 11:15 Cost, Use Cases & Drone Deployment 12:00 First Sales & Commercial Rollout 12:45 Market Size: Aviation & Drone Opportunity 13:20 Final Thoughts on Quantum Sensing 13:45 Speed of Innovation & Closingr
