   1. How do atomic clocks work, and why are they essential for GPS systems?
      • Atomic clocks rely on the stable vibrations of atoms (usually cesium or rubidium) to precisely measure time. GPS satellites use these clocks to synchronize signals and determine accurate positions.
   2. What makes quantum magnetometers so sensitive?
      • Quantum magnetometers exploit the quantum behavior of atomic spins or superconducting circuits to detect tiny magnetic fields, such as those produced by the human brain or buried archaeological artifacts.
   3. Can quantum-enhanced imaging reveal hidden structures in biological tissues?
      • Yes, quantum-enhanced imaging techniques like quantum illumination and ghost imaging can enhance resolution and penetrate deeper into tissues, potentially aiding medical diagnoses.
   4. How does uncertainty play a role in quantum sensing?
      • Uncertainty, as described by Heisenberg’s uncertainty principle, sets fundamental limits on how precisely we can simultaneously measure certain pairs of properties (e.g., position and momentum) in quantum systems.
