+## Beginners Level
+
+### Estimated Duration: 2–4 weeks  
+### Prerequisites:
+- Basic understanding of **Python**
+- Familiarity with **linear algebra** and **complex numbers**
+
+---
+
+### 💡What is Quantum Computing?
+Quantum computing uses the principles of **quantum mechanics** — the science of subatomic particles — to perform computations.  
+Unlike classical computers that use **bits (0 or 1)**, quantum computers use **qubits**, which can exist in multiple states simultaneously (known as **superposition**). This allows them to solve certain problems exponentially faster.
+
+**Why it matters:**  
+Quantum computing is reshaping industries like **cryptography**, **drug discovery**, **finance**, and **artificial intelligence**.
