With increasing efforts to built the world first quantum computer, solid state based technology using superconducting (SC) circuits as the building blocks for qubits is becoming the most promising implementation due to its scalability, ease of fabrication and short quantum gate times. These SC circuits can, however, have other applications such as hybrid quantum circuits, where the idea is to join them with non-SC systems. An example of such hybrid system consists of a ferromagnetic spin system coupled with a qubit, mediated by a microwave resonator (quantum magnonics).
In specific, my project is concerned with the characterisation of ferromagnetic samples (in particular, YIG thin films) at room and milliKelvin temperatures and their future integration in hybrid circuits.
