Quantum computers represent a groundbreaking advancement in technology, promising to solve complex problems that are beyond the reach of classical computers. Unlike classical computers, which process information in binary (0s and 1s), quantum computers leverage the principles of quantum mechanics to perform calculations at unprecedented speeds. How Do Quantum Computers Work? At the heart of quantum computing lies the quantum bit or qubit . Unlike classical bits that can be either 0 or 1, qubits can exist in a state of superposition , meaning they can be 0, 1, or both simultaneously. This allows quantum computers to process multiple possibilities at once. Quantum computers also use two other key principles: 1. Entanglement : Qubits can be linked, such that the state of one qubit is dependent on the state of another, even when they are far apart. 2. Quantum Interference : By carefully manipulating quantum states, quantum computers can amplify correct solutions and canc...
