Quantum Future with Jack: Sensing and Communications

Introduction

• Presenter: Jack
• Subject: Application of quantum mechanics in sensing and communications
• Audience: Digital entrepreneurs
• Objective: Understand real-world applications and transformative potential of quantum mechanics

Quantum Mechanics in Everyday Life

• Examples: Medical Imaging
  • fMRI (functional MRI)
  • PET scans (Positron Emission Tomography)
  • Originally NMR (Nuclear Magnetic Resonance) renamed to MRI (Magnetic Resonance Imaging)

Sensing

Thermometer Analogy

• Old Thermometer: Low sensitivity, limited range (0 to 20°F, 5°F increments)
• New Thermometer: High sensitivity, wide range (0 to 400°F, tenth of a degree)
• Analogy Purpose: Contrast classical vs. quantum sensing capabilities

Quantum Sensing Examples

• Quantum Illumination (Seth Lloyd)
  • Quantum radar can detect objects at much greater distances (e.g., 5x or 10x the range of classical radar)
  • Potential applications: Improved safety in airports, better detection systems
• Quantum Sensor (Startup cpin, University of Nottingham)
  • Size of a ballpoint pen; measures small fluctuations in magnetic fields caused by brain activity
  • Potential applications: Mobility in brain activity detection, more practical and affordable than current MEGs (Magnetoencephalography)

Communications

Historical Perspective on Networks

• Arpanet (1969): Early form of the internet, connected a few universities and labs
• Purpose: Connect multiple networks (internet as
