# Qiskit 101 — How I began my quantum computing journey?

Physics has always been the **love of my life ❤!**

I got introduced to quantum physics back when I was in my teens. In the movie, *The Theory of Everything*, in one of the dinner scenes, Hawking’s wife Jane was talking about how Hawking was trying to come up with a unified theory of the **BIG THINGS, **i.e. general relativity; and the **small things**, i.e. quantum mechanics.

This is when I became interested in black holes and quantum physics. I started studying quantum mechanics from **Stanford Lagunita**, in an online course. Back then I did not have a good background in math, so it was difficult to understand all the linear algebra and calculus.

A few years later, I was introduced to quantum computers. I learned that they could be the next “big thing” in the world of computing.

If we study classical computers, they work on binary digits, that is, **0 and 1.** At a certain time, the computation is either a zero or one. But in the case of quantum computers, it is a **superposition of 0 and 1.** This is because of quantum properties of **qubits**, which are used to represent bits of computation in quantum computers.

# What is Qiskit?

Qiskit is an open-source quantum development API, created by **Qiskit.org. **It is written majorly in Python and can be installed as a development package using:

`pip install `**qiskit**

The good developers and open-source contributors at Qiskit, have compiled a textbook on quantum development. With this textbook, one can learn about the basics of quantum computing using **Qiskit**.

The first unit of the Beta Textbook (the newer version of the textbook) covers **Introduction to Quantum Computing.** I studied about quantum computers, qubits, basic quantum mechanics, quantum gates, matrix transformations, quantum circuits, quantum entanglement and a searching algorithm called **Grover’s algorithm**.

I really loved the chapters on these individual topics. I am going to write more blogs on the Qiskit APIs and my projects!
