Abstract
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.
