How Quantum Sensors Work

Quantum Sensors Process Diagram
  1. Quantum State Preparation: Systems like atoms or photons are prepared in a quantum state, such as superposition or entanglement.
  2. Interaction with Environment: The quantum system interacts with the target property (e.g., magnetic field), altering its state.
  3. Measurement: Precise detection of the altered quantum state provides data on the measured property with high accuracy.
  4. Integration: Sensors are combined with classical systems for real-time data processing and practical deployment.
