In Module 2, we saw how single electron spins can be used to form qubits. However, spin qubits can be realized in other physical systems in addition to semiconductor quantum dots. This week, we will discuss one of these examples, nitrogen-vacancy centers in diamond.

NV centers, with their long-lived and controllable quantum states, are considered one of the most promising platforms for building the first scalable quantum internet. One of the main requirements of quantum networks is the ability to quickly create robust entanglement links. Check out this recent article published in Nature to discover how this can be realised in these diamond spin qubits.

Tim Taminiau, from TU Delft, will describe the unique features of this new type of qubit platform. Throughout two lectures, he will explain how we can define a spin system in diamond, how we can optically manipulate it, and what we need in order to build quantum networks for quantum computation and quantum communication.

Let’s begin Module 3!
