Superconducting spin qubits in planar Ge

In this project, we will work on creating a quantum bit that combines two advanced technologies: superconducting circuits and spin qubits, both of which are used to create state- of-the-art qubits on their own. By connecting a small, controlled area of a semiconductor, known as a quantum dot, with superconducting materials, we can create what`s called a superconducting spin qubit. This device will help us explore and understand the physics of spin-orbit coupling of two-dimensional Germanium holes gases. Once we have this device, we plan to study how stable the qubit is (its "coherence") and how quickly it can be operated. After that, we`ll work on connecting two of these qubits to each other to see if we can improve the performance of long-distance two-qubit gates. To investigate this, we will link them through a superconducting resonator, either inductively or capacitively coupling them to the resonator. This step is important for moving towards scalable qubits.
