Quantum computing is often portrayed as the frontier where the peculiarities of quantum mechanics intersect with revolutionary technological advancements. While the international narrative surrounding quantum computing highlights leading figures, institutions, and breakthrough events in the Western world, it’s crucial to uncover the lesser-known yet impactful contributions that India has made to this domain. This comprehensive exploration will delve into the micro-history of quantum computing in India, focusing on lesser-known events, leaders, places, and cultural developments that have significantly shaped the current landscape.
1. An Overview of Quantum Computing
1.1 Understanding Quantum Mechanics
The foundation of quantum computing lies in quantum mechanics, a branch of physics that explains the behavior of matter and energy at atomic and subatomic levels. Unlike classical computing, which uses bits as the smallest unit of data (either a 0 or a 1), quantum computing utilizes qubits, which can exist in multiple states simultaneously due to the principles of superposition and entanglement.
1.2 The Promise of Quantum Computing
Quantum computers have the potential to solve complex problems much faster than classical computers. They can revolutionize fields such as cryptography, drug discovery, optimization problems, and artificial intelligence. The exponential rise in interest from both governments and private organizations worldwide indicates the immense potential inherent in this technology.
