"Computer scientists have only begun to realize the potential of quantum computing and algorithms, where computers use quantum principles to store data in qubits. One thing that could help in the development of algorithms is the "quantum walk," which involves the movement of a particle as a superposition of all possible states. Until recently, quantum walks were a theoretical construct. However, according to Science, physicists in Germany are now able to make cesium atoms arranged in an optical lattice perform a physical quantum walk."
"In the Islamic Republic it is illegal to execute a young woman, regardless of her crime, if she is a virgin, he explained. Therefore a "wedding" ceremony is conducted the night before the execution: The young girl is forced to have sexual intercourse with a prison guard - essentially raped by her "husband." "I regret that, even though the marriages were legal," he said. Why the regret, if the marriages were "legal?" "Because," he went on, "I could tell that the girls were more afraid of their ‘wedding’ night than of the execution that awaited them in the morning. And they would always fight back, so we would have to put sleeping pills in their food. By morning the girls would have an empty expression; it seemed like they were ready or wanted to die."
