Quantum Computing: The Next Frontier in Technology
Quantum computing is one of the most exciting advancements in technology today. Unlike classical computers, which use bits as the smallest unit of data, quantum computers use qubits, harnessing the principles of quantum mechanics to solve complex problems much faster than traditional computers.
What is Quantum Computing?
Quantum computing leverages quantum mechanics, a fundamental theory in physics, to perform computations. While classical computers use bits (0s and 1s), quantum computers use qubits, which can exist in multiple states simultaneously thanks to two key quantum phenomena: superpositionand entanglement.
- Superposition: A qubit can represent both 0 and 1 at the same time.
- Entanglement: Qubits can be interconnected, meaning the state of one qubit can depend on the state of another, even if they are far apart.
Quantum vs. Classical Computing
| Feature | Quantum Computing | Classical Computing |
