Introduction Quantum computing is no longer just a concept—it’s becoming a reality. Unlike traditional computers that use bits to represent either 0s or 1s, quantum computers leverage qubits, which can exist in multiple states simultaneously thanks to quantum phenomena like superposition and entanglement. These capabilities allow quantum computers to solve complex problems at unprecedented speeds.
Understanding Quantum Computing The power of quantum computing comes from its ability to process information in parallel, unlike classical computers, which process data sequentially. Quantum computers use quantum gates to manipulate qubits, performing calculations that would take classical systems years or even centuries.
Key quantum principles driving advancements:
- Superposition – Qubits can represent multiple states at the same time, increasing computational efficiency.
- Entanglement – Quantum particles become interdependent, enabling faster and more secure information transfer.
- Quantum tunneling – Allows information to pass through barriers at the quantum level, improving problem-solving capabilities.
Applications of Quantum Computing
