| Description: | Processors based on quantum logic have the potential to solve highly complex problems more efficiently than classical digital processors. Among the various technological approaches to realizing this, silicon-based qubits represent a promising approach to overcoming the technological and physical hurdles of existing quantum processors, particularly with regard to system scaling. This project aims to develop novel quantum systems based on indium acceptors in silicon. Successful implementation of this approach will contribute to improved modularity and flexibility of silicon-based qubits. A key advantage is that the technological building blocks to be used have already been demonstrated, and the underlying properties of the indium centers warrant further investigation. In this project, indium-based acceptor defects are to be realized for the first time as readily accessible quantum systems. This will be achieved by integrating the defects directly into a weakly amplifying photodiode to detect the photoluminescence emitted by the indium color center. Based on previous work, indium is a promising candidate as a qubit in silicon and a complementary building block for silicon-based quantum computers. |
