The power and high information capacity of entangled states has been so far demonstrated in several areas of quantum communication and quantum computing. We recently developed new techniques for precise optical measurement in life sciences and optoelectronics that take advantage of quantum entanglement and exceed traditional approaches both in resolution and in the amount of obtained information about the system under evaluation.
We review our latest results in engineering special entangled-photon states with particular spectral, spatial, and polarization characteristics that enhance performance of quantum cryptography and such novel measurement technologies as quantum optical coherence tomography and quantum ellipsometry.
