Review Questions
How does quantum entanglement contribute to the advancements in quantum imaging sensing techniques?
Quantum entanglement plays a crucial role in enhancing quantum imaging sensing techniques by allowing correlated photons to share information about their states. When entangled photons are used in imaging, they can provide information that exceeds the classical limits of resolution and sensitivity. This capability enables the reconstruction of images from fewer photons or under low-light conditions, significantly advancing fields like biomedical imaging and remote sensing.
