Introduction to Quantum Computing
Quantum computing is an emerging field that combines principles from quantum mechanics and computer science to potentially revolutionize computing as we know it. It harnesses the fundamental properties of quantum physics to perform complex calculations and solve problems that are currently infeasible for classical computers.
The Basics of Quantum Computers
Unlike classical computers that rely on bits to store and process information using binary codes (0s and 1s), quantum computers use quantum bits or qubits. Unlike classical bits, qubits can exist in multiple states simultaneously due to a quantum mechanical phenomenon called superposition.
Superposition and Entanglement
Superposition allows qubits to be in a state that is neither 0 nor 1 but a combination of both. This enables quantum computers to perform parallel computations and explore multiple possibilities simultaneously. Additionally, qubits can also be entangled, meaning their states become interconnected, resulting in a correlation that persists even if they are physically separated.
Quantum Computing Algorithms
