# Quantum Metrology And Sensing Techniques

## Core Concepts

Quantum metrology and sensing leverage the principles of quantum mechanics to achieve measurement precision beyond the capabilities of classical techniques. This field focuses on enhancing the sensitivity and accuracy of measurements of physical quantities like time, frequency, magnetic fields, gravitational fields, and temperature.

**Key Principles:**

*   **Quantum Superposition:** Utilizing the ability of quantum systems to exist in multiple states simultaneously to explore a wider range of possibilities during measurement.
*   **Quantum Entanglement:** Employing correlations between quantum particles to reduce noise and enhance sensitivity. Entangled states can exhibit correlations stronger than any classical system, leading to improved measurement precision.
