Quantum computing is a revolutionary field that leverages the principles of quantum mechanics to solve problems beyond classical computers' capabilities. Here's a concise overview:
🔑 Core Concepts
- Qubits: The fundamental unit of quantum information, unlike classical bits which are 0 or 1, qubits can exist in a superposition of states.
- Entanglement: A phenomenon where qubits become interconnected, allowing instantaneous correlations between states.
- Quantum Gates: Manipulate qubits through operations like Hadamard (creates superposition) or CNOT (creates entanglement).
📚 How It Works
- Quantum State: Represented as a vector in a complex Hilbert space (e.g., $|0\rangle$, $|1\rangle$, or $ \frac{1}{\sqrt{2}}(|0\rangle + |1\rangle) $).
- Measurement: Collapses the superposition into a classical bit, with probabilities determined by quantum amplitudes.
- Interference: Quantum states can constructively or destructively interfere, enabling algorithms to amplify correct answers.
