Generation and interference effectes with quantum states of light

The study of quantum states of light is a rapidly developing field of
research. In recent years, scientists have begun to find situations where
quantum mechanically systems provide unique solutions to modern
technological problems. Quantum information processing (QIP) is an exciting
example of promising applications of such systems.

Within the NanoScience Group, we are exploring the quantum correlation
properties of light generated by the non linear process of Spontaneous
Parametric Down Conversion.
The mechanism generates two infrared photon, with peculiar quantum
properties, from the splitting of a single pump photon at 775 nm.
We are investigating their time-energy entanglement by performing
coincidence measurements and demonstrating nonclassical interference in a
free space Mach Zehnder Interferometer.
