Quantum beyond Nano

In the beginning of the 20th century, quantum physics emerged as the ultimate principle of nature and universe, and became the basis of modern science and technology. Quantum physics began as an explanation of how material and light interact, provided new ways of synthesizing materials, and revolutionized the information technology in the second half of the 20th century through the invention of semiconductor devices, laser and others. Nanotechnology, which has pursued miniaturization through quantum physics, cannot avoid the fatal limit of ambiguity between 0 and 1 due to the quantum uncertainty principle. Quantum physics, which so far has been the principle for hardware only, opens a new era of quantum information technology providing the principles for not only hardware, but also software and operating systems. While nanotechnology takes the passive stance to avoid the quantum uncertainty principle, quantum information science actively uses quantum principles and introduces new technologies that are impossible to achieve with nanotechnology including quantum computers, quantum cryptography, quantum teleportation, quantum imaging, quantum metrology and quantum sensors.
