Quantum states are in many ways different from information stored in classical systems - quantum states cannot be cloned and quantum information cannot be erased. However, it turns out that quantum information can be transmitted and replicated by combining a quantum channel and a classical channel - a process known as quantum teleportation. Bell states … Continue reading Quantum teleportation

# Kubernetes services and load balancers

In my previous post, we have seen how we can use Kubernetes deployment objects to bring up a given number of pods running our Docker images in a cluster. However, most of the time, a pod by itself will not be able to operate - we need to connect it with other pods and the … Continue reading Kubernetes services and load balancers

# Kubernetes 101 – creating pods and deployments

In the last posts, we have seen how we can set up a Kubernetes cluster on Amazons EKS platform and spin up our first nodes. Today, we will create our first workloads and see pods and deployments in action. Creating pods We have already introduces pods in an earlier post as the smallest units that … Continue reading Kubernetes 101 – creating pods and deployments

# Python up an EKS cluster – part II

In the last post, we have seen how Python can be used to control the generation of an EKS cluster. However, an EKS cluster without any worker nodes - and hence without the ability to start pods and services - is of very limited use. Today, we therefore take a look at the process of … Continue reading Python up an EKS cluster – part II

# Python up an EKS cluster – part I

When you want to try out Kubernetes, you have several choices. You can install Kubernetes in a cluster, install it locally using Minikube, or use one of the Kubernets offerings of the major cloud providers like AWS, GCP or Azure. In this post, we set up a Kubernetes cluster on Amazons EKS platform. As I … Continue reading Python up an EKS cluster – part I

# Factoring integers on a quantum computer with Qiskit

After all the work done in the previous posts, we are now ready to actually implement Shor's factoring algorithm on a real quantum computer, using once more IBMs Q Experience and the Qiskit framework. First, recall that Shor's algorithm is designed to factor an integer M, with the restriction that M is supposed to be … Continue reading Factoring integers on a quantum computer with Qiskit

# Implementing the quantum Fourier transform with Qiskit

The quantum Fourier transform is a key building block of many quantum algorithms, from Shor's factoring algorithm over matrix inversion to quantum phase estimation and simulations. Time to see how this can be implemented with Qiskit. Recall that the quantum Fourier transform (or, depending on conventions, its inverse) is given by $latex |x \rangle \mapsto … Continue reading Implementing the quantum Fourier transform with Qiskit

# Running the Deutsch-Jozsa algorithm on IBMs Q experience

In one of the previous posts, we have looked at the basics of the Qiskit package that allows us to create and run quantum algorithms in Python. In this post, we will apply this to model and execute a real quantum algorithm - the Deutsch-Jozsa algorithm. Recall that the Deutsch-Jozsa algorithm is designed to solve … Continue reading Running the Deutsch-Jozsa algorithm on IBMs Q experience

# Using Python to access IBMs quantum computers

In a previous post, we have looked at IBMs Q experience and the graphical composer that you can use to build simple circuits and run them on the IBM hardware. Alternatively, the quantum hardware can be addressed using an API and a Python library called Qiskit which we investigate in this post. Installation and setup … Continue reading Using Python to access IBMs quantum computers

# Shor’s quantum factoring algorithm

Until the nineties of the last century, quantum computing seemed to be an interesting theoretical possibility, but it was far from clear whether it could be useful to tackle computationally hard problems with high relevance for actual complications. This changed dramatically in 1994, when the mathematician P. Shor announced a quantum algorithm that could efficiently … Continue reading Shor’s quantum factoring algorithm
