Experimental generation of quantum entanglement and testing fundamentals of quantum physics

Quantum entanglement of photons is of a great importance in the quantum optics and it is used in teoretical and experimental testing of fundamentals of quantum physics, especially in the fields of quantum cryptography, quantum teleportation and the development of quantum computers. Photons are perfect for a quick, efficient and secure way to transfer information considering the speed of data transfer and almost non existing interaction with its environment. Because of that they have a huge role in the development of quantum communication networks. On this poster description of an experimental setup for realization of polarization entangled photon pairs of the wavelength of 810 nm is shown together with the results of the experimental measurements of correlation of polarized states. Also, the experiment confirmed the violation of Bell’s inequality in CHSH form of 114 standard deviations from the classical limit. The experiments have been done at Center of Excellence for Advanced Materials and Sensing Devices (CEMS), Photonics and quantum optics research unit at the Ruđer Bošković Institute in Zagreb.
