The SparQ project, through the collaborative efforts of XeedQ GmbH, Ionoptika, University of Surrey, and Fraunhofer Institute IAF, aims to push the boundaries of current technology and achieve several key goals in the field of solid-state qubit fabrication. The goal of the SparQ project is to develop a ground-breaking tool or method that combines the partners’ diverse areas of expertise.

These include:

• Developing a completely novel ion beam system, uniquely capable of implanting a variety of both liquid metal and plasma ion species into diamond substrates. This innovation will enable the accurate positioning of color centers in diamond substrates, with a target accuracy below 25 nm, moving beyond the state-of-the-art in qubit fabrication.
• Enhancing spin qubit properties, such as coherence time and photostability, by addressing ion implantation-induced challenges and optimizing growth procedures and surface passivation methods.
• Investigating the potential of nitrogen and tin-based color centers for stable operation at low temperatures, enabling more efficient and effective quantum computing.
• Demonstrating the effectiveness of the developed processes and techniques through multiple experimental runs, paving the way for future advancements in quantum computing and simulation platforms.
