This dissertation investigates two quantum systems with entangled photons: the quantum state tomography system and the quantum key distribution system. In the beginning, it covers fundamentals of quantum mechanics and generation mechanisms of entangled photons as a prerequisite for enabling the quantum state tomography process as well as designing quantum key distribution protocols. For quantum state tomography, we researched the linear inversion method, which provides a fast way to reconstruct a quantum state, but the reconstruction result may be unrealistic. This dissertation also presents a detailed theoretical and experimental approach using the maximum likelihood estimation method for two-qubit quantum state tomography. It investigates the limitations that potentially affect the accuracy of the density matrix reconstruction, such as coincidence count detection errors from the detection unit, polarization controller error from waveplates, and coincidence to accidental counts ratio change from the entangled photon source. The quantum state tomography with deep learning method for many-qubit systems is also discussed. For quantum key distribution, this dissertation explains multiple protocols and established an error correction post-processing procedure. An original key distribution protocol is proposed along with the design of several quantum optical circuits that create and process hyper- entangled states. These circuit designs can be used as an essential part for separating entangled photons and for construction of a safe one-time pad cryptographic key. In order to verify that our innovative protocols are compatible with free-space links, entangled photon transmission in turbulent atmosphere is also analyzed. In addition, we performed progressive measurements on our quantum optical circuits to prove integrity of entanglement after propagation. The results indicate that several applications of our quantum circuits, such as photon routers and multi-access quantum receivers, are also plausible. For the latter, we investigated different scenarios of off-axis transmission/reception and performed both theoretical and experimental analysis of our quantum circuits. Several practical experimentation techniques for quantum systems are also discussed at the end.
