Since 1960, the potential of world development has kept growing exponentially, which allow computers to get smaller and more powerful at the same time. However, this process is about to meet physical limits, and it is time to invent a new type of computer. The ultimate solution for this problem is Quantum Computers.
People, nowadays, starts to rely their life on computers. Even though technology of computers have exponential development growth, the massive amount of processing power generated by computer manufactures has not yet been able to quench our thirst for speed and computing capacity. Furthermore, after the invention of Artificial Intelligence, also known as AI, has been announced to the world, computer software engineering companies required better quality of hardware. For instance, AlphaGo, computer program which is developed by Google DeepMind in London to play the board game Go, requires around 1,200 computers in a row arrangement. In those reasons, however, the cryptography part plays one of the most important reason for development of quantum computers.
So far, unbreakable cryptography has not been invented yet. However, the ultimate encryption system that human species invented so far is unfortunately breakable. In fact, with Bruce Force Attack, a trial-and-error method used to obtain information such as a user password or personal identification number with generating a large number of consecutive guesses as a value of the desired data, every single encryption system is useless.
Even though Quantum computer is remain as a theory, the time that quantum computer become part of our life is not that far away. In fact, lots of computer companies, including Google, start to take a first step.
