Quantum sensing and quantum-enhanced measurement techniques leverage unique quantum phenomena such as superposition, entanglement, and squeezing—to achieve sensitivities beyond the limits of classical devices. By exploiting these properties, quantum sensors can detect extremely weak signals, including magnetic and electric fields, temperature variations, and forces, with unprecedented precision. Recent advances in solid-state qubits, trapped ions, nitrogen vacancy centers in diamond, and superconducting circuits have enabled practical implementations of quantum-enhanced measurements in both laboratory and field settings. These techniques have transformative potential in areas such as biomedical imaging, navigation, metrology, fundamental physics tests, and materials characterization. This review highlights the principles, state-of-the-art implementations, and emerging applications of quantum sensing, emphasizing the interplay between quantum coherence, noise suppression, and device engineering in achieving high-precision measurements. Quantum sensing and quantum-enhanced measurement techniques exploit fundamental quantum phenomena such as superposition, entanglement, and quantum squeezing—to achieve measurement precision beyond classical limits. These approaches enable the detection of extremely weak signals, including magnetic and electric fields, temperature variations, and forces, with unprecedented sensitivity. Advances in platforms such as nitrogen-vacancy centers in diamond, trapped ions, superconducting circuits, and ultracold atoms have paved the way for practical quantum sensors capable of high-precision metrology in both laboratory and real-world environments. By integrating quantum coherence with noise mitigation strategies, quantum enhanced measurements are transforming applications in navigation, biomedical imaging, fundamental physics, materials characterization, and emerging quantum technologies. This review summarizes the underlying principles, recent experimental implementations, and future
prospects of quantum sensing, highlighting its potential to redefine precision measurement across multiple disciplines.
