The Quantum Computing Revolution

Image
The emergence of quantum computers signifies a transformative leap in computational technology, promising advancements that could surpass the profound impact of traditional digital computers. Quantum computing operates on the principles of quantum mechanics, utilizing the behavior of atoms and particles to perform calculations far beyond the capabilities of conventional systems. This post is the excerpts from the video talk by Dr. Michio Kaku available on BIG THINK youtube channel. The Race for Quantum Computing The competition to perfect quantum computers involves all major technology companies and national governments. Non-participation in this race could lead to Silicon Valley becoming analogous to the Rust Belt. Security agencies, including the FBI and CIA, are closely monitoring developments in quantum computing due to its potential to crack codes based on digital technology. Historical Context of Computing Three stages of computing: Analog Computers: Originated over 2,000 yea...
