Revolutionizing the Future of Technology

Quantum computing is poised to transform industries by solving complex problems beyond the capabilities of classical computers. Unlike traditional computers that rely on binary bits (0s and 1s), quantum computers use qubits, which leverage superposition and entanglement to perform calculations at unprecedented speeds. This emerging technology has the potential to revolutionize fields such as cryptography, artificial intelligence, drug discovery, and climate modeling. Data Science Course in Pune

1. Understanding Quantum Computing

a) Classical vs. Quantum Computing

Feature	Classical Computing	Quantum Computing
Data Representation	Uses bits (0 or 1)	Uses qubits (0, 1, or both simultaneously)
Processing Power	Performs tasks sequentially	Can perform multiple calculations simultaneously
Speed	Limited by transistor scaling	Exponentially faster for complex problems
Memory Requirement	Grows linearly with problem size	Needs fewer qubits for massive computations

b) Core Principles of Quantum Computing

Superposition: A qubit can exist in multiple states at the same time, allowing quantum computers to explore many solutions simultaneously.
Entanglement: Qubits can be correlated regardless of distance, enabling faster communication and computations.
Quantum Interference: Allows quantum algorithms to cancel out incorrect solutions while reinforcing correct ones.

2. Key Applications of Quantum Computing

a) Cryptography & Cybersecurity

Traditional encryption methods like RSA and ECC rely on the difficulty of factoring large numbers.
Quantum computers can break these encryptions using Shor’s Algorithm, posing security risks.
Post-quantum cryptography (PQC) is being developed to counter quantum threats.
