WG1 will start by compiling an inventory of technological issues, which are of concern for most research groups. Information will then be gathered on the various items to build a common knowledge basis. During the annual work group meeting, best practice will be exchanged and a common operational task will be discussed for the following year. This WG has two tasks: tackling cutting edge technological obstacles in a joint manner, to guarantee progress through common means and by simplifying the access to key technologies and experiments, promote the use of ion trapping in a large number of domains. The milestones of this WG are common protocols for ion trap development, a standardisation of general components for ion trap experiments, and compilation of a standard simulation software package.
The main task of WG2 is to develop tools and processes for high precision measurements. The first milestone of this WG is the set-up of a database of all experimental, theoretical and simulation results concerning systems for precision measurements and sensors. Further milestones are the proposal, development and realisation of experimental and/or numerical solutions for missing items in the database, and finally the deduction of “universal” procedures and technologies. The annual WG assembly will discuss the proposals of new devices and eventually coordinated efforts to develop these.
A third workgroup WG3 will focus on the task of proposing novel protocols for quantum control experiments with trapped ions. This entails the development of high fidelity protocols for quantum gates and their implementation within specific ions. This requires a permanent dialogue between theory, simulation and experiment to propose original and innovating solutions. Milestones of this WG are the development of a common numerical code to simulate ion response to a control, its application to different ions with various energy level schemes, as well as the study of dynamics and thermodynamic effects.
The efforts of the workgroup will concentrate on the task of advancing the experimental methods to couple trapped ions to other quantum systems, such as neutral atoms or optical cavities. The milestones of this WG include implementation of new experimental approaches to study cooling, ion-neutral interactions, collisions and chemical reactions. In addition, standardised designs, technologies and components for experiments of ions in optical cavities will be compiled and standard components will be shared. Furthermore, other hybrid systems (such as ion-superconductor and ion-microwave systems) and their applications will be explored.
