What is Quantum Computing?
Think of a Coin
A normal computer is like a coin lying flat. It's either heads (1) or tails (0). Simple!
Why Does That Help?
Imagine searching a library of 1 million books. A normal computer reads them one by one.
Quantum Speed
Quantum computers solve certain problems millions of times faster than any classical machine.
Qubit
The quantum version of a bit. Instead of just 0 or 1, a qubit can be 0, 1, or both at once until you look at it!
Superposition
Like Schrödinger's cat — the qubit exists in multiple states simultaneously until measured. This is where quantum power comes from.
Entanglement
Two qubits can be linked together — when you measure one, the other instantly "knows" what to be, no matter how far apart!
💻 Classical Computer
- Uses bits: 0 or 1
- One answer at a time
- Great for everyday tasks
- Your laptop, phone, tablet
- Tries every option one by one
VS
⚛️ Quantum Computer
