Introduction to IBM Qiskit
Instalation
The safe way to use the Qiskit is using conda virtual environment. After installing Anaconda 3, you do the following commands:
-
conda create -n qiskit_env python=3
-
source activate qiskit_env
Now you install Qiskit:
-
pip install qiskit
-
pip install qiskit-terra[visualization]
To put this environtmen on your jupyter notebook environment you need to type the following comands:
-
conda install jupyter
-
conda install nb_conda
-
conda install ipykernel
-
python -m ipykernel install --user --name qiskit_env
In order to test if the qiskit is installed you import on your python enviroment.

Initial Tutorial
In this code you will learn:
- Build a simple circuit that creates a bell state using Hadamard and C-Not gates. - Simulate your circuit theoretically to get the state vector. - Build a real circuit that measures your Qubits in order to give bits of information. - Simulate measurement circuits that can be applied to real quantum computers. - Run your circuit in the a Real Quantum Computer. -
Deutsch Algorithm
In this code you will see the first application of a quantum computer predicting if a boolean function is balanced or constant with only one query.
-
Grover Algorithm
In this code you will learn the main quantum search algorithm.
-
Quantum Fourier Transform
In this code you will learn one of the building blocks of inumerous algorithms in Quantum Computing.
-
Quantum Phase Estimation
In this notebook you will learn about a way to get eigenvalues from a given state. This is an important subroutine that is used on various quantum algorithms.
-
Tomography
In this notebook you will learn about Quantum State Tomography, that is really important to characterize unknown quantum states.
-
Quantum Counting
In this notebook we will learn a way to count how many solutions are on a given quantum search algorithm.
