Owing to advancements in quantum computing technologies, classically encrypted information can be quickly decrypted in the foreseeable future, posing a challenge to information security. The realization of quantum networks will be needed to ensure the security of information transfer, through the use of quantum cryptography. In order to overcome losses and to increase the range of quantum networks, quantum repeaters will be required. Quantum repeaters extend the transmission distance of quantum information by performing entanglement swapping, a fidelity-reducing operation. As such, entanglement distillation is key in restoring the fidelity of entangled states and in building a practical, working quantum network. In this thesis, we studied the proposed architecture of a quantum network and discussed the quantum mechanics behind it. We also simulated an experimental entanglement distillation protocol and explored the relationship between its probability of success and output state fidelity. |
