Quantum computing is a rapidly growing field that promises to solve complex problems much faster than classical computers.
🧠 What is Quantum Computing?
Quantum computing is based on the principles of quantum mechanics, a branch of physics dealing with the behavior of particles at atomic and subatomic levels.
🔁 Classical vs. Quantum
| Classical Computer | Quantum Computer |
|---|---|
| Uses bits (0 or 1) | Uses qubits (0, 1, or both — superposition) |
| Sequential processing | Parallelism via entanglement and superposition |
| Deterministic | Probabilistic outcomes |
🔹 Qubits
Qubits are the building blocks of quantum computers. Unlike classical bits, qubits can be in a state of 0, 1, or both simultaneously — this is called superposition.
Example:
A single qubit can be represented as:
