One of them is detected to be green, leaving the other three entangled as a W state, which is comprised of all possible iterations of two red photons and a green photon at once. Compared to other types of three-particle entanglement, the W state is useful for quantum communication in that, if one of the photons is lost, the other two retain some entanglement, meaning the communication is able to continue.

The procedure that leads to the construction of a polarisation-based entangled system is discussed by considering some of the measurement techniques, which can be applied to study fundamental quantum mechanics and its applications in quantum communication. This thesis consists of a set of experiments to validate the entanglement of single photon pairs. The rst experiment realised by generating of polarised based entangled photon pairs.
The quantum correlation between the entangled photon pairs have been tested by measuring the visibility of the system and by verifying the maximal violation of CHSH Clauser, Horne, Shimony and Holt inequality. In the second experiment, the delity of the system has been measured by carrying out the state tomography to reconstruct the two-photon density matrix and consider the interference e ect of two photons. This helps to study the preservation of the quantum state during the propagation.
The education ecosystem is not keeping pace as society transitions from an industrial to knowledge economy and too many have been left behind. Ecosystem. in the process of taking down the Christmas tree, we managed to entangle the string of lights into a hopeless mess of wires the young runaway gradually.
