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:

1. conda create -n qiskit_env python=3

2. 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.
