Quantum mechanics has emerged as a state-of-the-art trend in the scientific world. Thanks to steady yet brilliant developments in nanotechnology, this results in a phenomenal technology that can be directly applied to the real world. For starters, the technology encompasses the use of passwords, semiconductors, and sensors. It can be regarded as surpassing Einstein's theory of relativity. As a non-science major, simply out of curiosity, I browsed through a variety of data on this subject.
