In some of the last posts in my series on quantum computing, we have discussed how NMR (nuclear magnetic resonance) technology can be used to implement quantum computers. Over the last couple of years, however, a different technology has attracted significantly more interest and invest - superconducting qubits. What are superconducting qubits? To start with … Continue reading Superconducting qubits – an introduction
In one of the previous posts, we have learned how to expose arbitrary ports to the outside world using services and load balancers. However, we also found that this is not very efficient - in the worst case, the number of load balancers we need equals the number of services. Specifically for HTTP/HTTPS traffic, there … Continue reading Managing traffic with Kubernetes ingress controllers
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
In this post, we will look in some more detail into networking in a Kubernetes cluster. Even though the Kubernetes networking model is independent of the underlying cloud provider, the actual implementation does of course depend on the cloud provider which communicates with Kubernetes through a CNI plugin. I will continue to use EKS, so … Continue reading Watching Kubernetes networking in action
In my last post on NMR based quantum computing, we have seen how an individual qubit can be implemented based on NMR technology. However, just having a single qubit is of course not really helpful - what we are still missing is the ability to initialize several qubits and to realize interacting quantum gates. These … Continue reading NMR based quantum computing: gates and state preparation
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
In the previous post, we have sketched the basic ideas behind NMR based quantum computation. In this post, we will discuss single qubits and single qubit operations in more depth. The rotating frame of reference In NMR based quantum computing, quantum gates are realized by applying oscillating magnetic fields to our probe. As an oscillating … Continue reading Single qubit NMR based quantum computation
