Quantum entanglement is an essential resource in quantum information processing, such as quantum communication and quantum computing. Although entanglement is critical for practical implementations in these fields, creating and transmitting entanglement without altering the states is challenging. External noise may destroy or weaken the entanglement. Consequently, there is a need for methods to improve entanglement. Entanglement distillation is an effort to address this issue. It is a process where, probabilistically, a smaller number of strongly entangled states are created from a fixed number of noisy entangled states. This process is carried out using only local operations and classical... 

One of the most important steps in the process of network forensics is attacker attribution and tracing the victims of the attack. In some situations, there is no other information to track the attacker except the payload of packet. Network security professionals have introduced payload attribution techniques to attribute this type of attacks. In payload attribution techniques, a history of network traffic is stored so that after the attack, it can be queried to trace the source and destination of excerpts. Due to the high volume of traffic in today's networks, payload attribution techniques should be able to store traffic in compressed format so that querying on this data be done easily at...
