At first, I knew I wanted to do an extended essay on computer science. I believe that computer science will an area of knowledge that can push forward our technology and major scientific discoveries due to the complex nature of the subject, but also the applicability of it on the real world. I considered delving into artificial intelligence and parallel computing, but from my research, I found that quantum computing is an area that is difficult yet fascinating. I thought that exploring a quantum algorithm through experimentation would be the best way to further my learning. After researching more, I was interested in Shor’s law as it has real world application that can affect our daily life. Through online research, I utilized a quantum environment, qiskit, to program and the IBM QX computer to put the algorithm into action. Based on the output of the program, I found that I can measure the reliability of the algorithm.
