In this tutorial you will see how a specific type of error called a phase flip error can be corrected using a quantum circuit known as the phase flip code.
This tutorial will introduce the user to the CNOT gate and how to implement it on IBMs quantum computers
The CNOT gate is a mulit-qubit gate that consists of two qubits. The first qubit is known as the control qubit and the second is known as the target qubit. If the control qubit is |1〉then it will flip the targets qubit state from |0〉to |1〉or vice versa.
In this article we will explore the process of Test Driven Development (TDD) and how you can use it to create reliable and dependable software.
Test Driven Development is a development process whereby feature specifications are implemented using unit testing before the software is fully developed. This is in contrast to a development first lifecycle where software is developed first and then the functionality tested using unit tests.
In this article we will explore the five SOLID design principles and how you can use them to make your code more robust and maintainable.
Solid is a set of five design principles devised by Robert C. Martin in his 2000 paper Design Principles and Design Patterns. In the paper Martin outlines the symptoms and causes of software rot and how these can be remedied with five object oriented class design principles.
Note however that in his paper these principles did not use the SOLID acronym. This term was keyed later in 2004 by Michael Feathers.
In this tutorial we will see how to construct an integer comparator in Qiskit for IBM quantum computers.
An integer comparator is a circuit that compares two integers. In Qiskit the integer comparator circuit relies on two’s complement implementation of binary subtraction.
In this tutorial we will create a web application that allows users to solve logical expressions using Grover’s search on IBM’s quantum computers. This web application will consist of a backend and frontend.
In this tutorial we will see how to obtain the unitary matrix of any quantum circuit in Qiskit.
In quantum computing unitary matrices are very important as they describe how quantum logic gates and circuits affect qubit states. However with large quantum circuits it can be difficult to derive the unitary matrix by hand.

In this tutorial we will explore the effects of T1 relaxation on IBM quantum computers in Qiskit.
What is T1 relaxation time?
Current superconducting qubits are very susceptible to decoherence due to its external environment. One example of decoherence is thermal relaxation.
Also known as T1 relaxation time this is where a qubits state to decays from 1 to 0 within a certain amount of time.

In this tutorial we will explore Rabi oscillations and how to model them on IBM quantum computers with Qiskit.
A Rabi oscillation is where a two level quantum system constantly oscillates between it’s ground state and an excited due to a driving field. For example when under exposure from a laser an atom will emit and absorb photons at a steady pace.
In this tutorial we will explore how to solve k-SAT problems using Grovers Search on IBM’s Quantum computers in Qiskit. The k-SAT problem is a Boolean satisfiable problem with k literals. Given a Boolean formula consisting of a number of clauses each with k literals the goal is to find what inputs will satisfy the problem.
