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.

Alexander V. Sergienko (e-mail: alexserg@bu.edu; URL: http://people.bu.edu/alexserg) received his M.S. and Ph.D. degrees in Physics from the Physics Department of Moscow State University in 1981 and 1987, respectively. After spending 1990-1991 academic year at the University of Maryland College Park as a Visiting Professor he joined the University of Maryland Baltimore County as a Research Assistant Professor in 1991. In 1996 Prof. Sergienko has joined the Faculty of the Department of Electrical and Computer Engineering at Boston University. Professor Sergienko is currently holding joint appointments in the Department of Electrical & Computer Engineering and in the Department of Physics. He is also a co-Director of the Quantum Imaging Laboratory at Boston University.
