India's Quantum Computing Revolution

The Rise of Quantum Computing

Quantum computing is an innovative field that holds the potential to transform various industries. It has sparked a global race towards technological dominance. Unlike classical computers, which operate using binary bits, quantum computers utilize qubits, enhancing their problem-solving speed and efficiency.

Differences Between Classical and Quantum Computing

• Processing Units: Classical computers rely on binary bits (0s and 1s), while quantum computers use qubits, allowing them to represent 0, 1, or both at once, a phenomenon known as superposition.
• Data Processing: Classical systems process data sequentially, but quantum computers handle data in parallel, resulting in significantly faster computations.
• Problem Solving: Classical computing approaches problems linearly, whereas quantum computing employs multidimensional quantum states for rapid and intricate calculations.
• Applications: Classical systems struggle with complex optimization and probabilistic problems, while quantum computing excels in areas such as optimization, cryptography, drug discovery, artificial intelligence, and weather modeling.
