Project QSea I & II: Kick-off for a modular and scalable ion trap quantum computer from Hamburg

On the way to the industrial use of quantum computing, the scalability of quantum processors is one of the biggest challenges. With our ion trap project QSea II, we are expanding our know-how in this area together with our industrial partners. Until its completion, QSea I will very soon have a working 10-qubit demonstrator at our disposal.

At the end of October, we commissioned five industrial partners to develop quantum computers based on ion traps. After the Toccata, Legato and Xaphiro projects, the QSea I and QSea II projects have now started work with an online kick-off event. This means that all ion trap projects are active at the Hamburg site.

For the QSea I project, we commissioned the NXP × eleQtron × ParityQC consortium to develop a ten-qubit quantum processor. In just one year, users at DLR will be gaining experience with ion trap systems on it and using the system for their research projects.

At the same time, the consortium is developing QSea II, a modular, scalable quantum computer based on ion traps. The goal is to interconnect multiple QSea chips into a universal quantum computing structure that can later grow to many chips with thousands of qubits. An important prerequisite for this scalability is the integration of electronic components into the chip of the quantum computer.

Ion trap competence for Hamburg

With no fewer than five ion trap projects, our innovation center in Hamburg is becoming an important location for ion trap technology in Germany. Because industry, research and application development come together there, we expect an intensive exchange and effective technology transfer from basic research to industry to application. One example of this is our QCI project TeufIQ from the DLR Institute for Quantum Technologies, which on the one hand offers technological support for the provision of processes for the production of ion traps and on the other hand promotes its own technological innovations.

“With QSea I, we will have a quantum computer demonstrator in just one year that we can start working with straight away.”
