Quantum computers differ from classical computers by using qubits instead of bits, enabling superposition and entanglement for faster computations. Quantum algorithms like Shor's and Grover's revolutionize problem-solving, promising a future of unprecedented technological advancements.
Quantum vs Classical
Expand
Quantum computers operate on the principles of *quantum mechanics*, using **qubits** that can exist in multiple states simultaneously, [unlike classical bits that are either 0 or 1](https://library.fiveable.me/quantum-computing/unit-1/classical-vs-quantum-computation/study-guide/e5WjGIjJO9fn5InY). [This allows quantum computers to perform certain tasks exponentially faster than classical computers](https://www.researchgate.net/post/What_is_quantum_computing_and_how_does_it_differ_from_classical_computing). While classical computers rely on binary logic gates, [quantum computers use quantum gates that manipulate the probability amplitudes of states](https://www.linkedin.com/pulse/quantum-computers-vs-classical-technical-exploration-ismail-esgzf).

Entanglement Wonders
Entanglement is another pivotal concept in quantum mechanics, where qubits become interconnected regardless of physical distance. This interconnectedness allows quantum systems to exhibit correlations unattainable in classical systems, enhancing computational efficiency. By leveraging entanglement, quantum computers can perform collective operations on qubits, unlocking new algorithmic potentials. Expand
Quantum Algorithms
Quantum algorithms like Shor's Algorithm and Grover's Algorithm redefine problem-solving paradigms. Shor's Algorithm revolutionized cryptography by efficiently factoring large numbers, a task considered infeasible for classical computers. Grover's Algorithm accelerates database searches, enabling faster data retrieval compared to classical search algorithms.
