Expérimental
Quantum computing is currently pushing further the frontier of information technology. Among other fields, solid-state hole-spin qubits are a promising research area. Recently, we reached the strong-coupling regime between the spin of a single hole trapped inside the channel of a silicon transistor and a single microwave photon enclosed in a superconducting resonator [1], realizing a hybrid spin cQED architecture. The aim of this project is to advance the field of spin cQED by fabricating superconducting resonator arrays made of superconducting thin films of NbN [3,4]. These arrays should allow to study the interaction between one spin and several microwave photonic modes, a first step toward quantum simulation. During the master project, you will participate to the development of new high quality resonators, which includes designing, modelling and measuring them. Our research team is part of the French national “Plan Quantique” and we strongly collaborate with in-house theory colleagues. During the master project, you will collaborate on a daily basis with a lively team of three permanent researchers and three PhDs. You will participate to the development of new samples and you will learn to cool down samples to reach cryogenic temperatures. State-of-the-art DC and RF measurements will be used. [1] Nat.
