We are delighted to welcome Masters level students (ArTeQ) to discover superconducting quantum qubits in a brand new hands-on assignment. This TP was developed by Marcelo Goffman (CEA Saclay – SPEC – Quantronics) professor attached to the superconducting Qubit project at the University of Paris-Saclay, in collaboration with the N2S group (Julien Basset, Julien Gabelli, Jerome Esteve) and Meydi Ferrier (LPS – Meso) with partial support from Quantum Saclay.
In this lab, students dive into the quantum hardware required for the coherent manipulation and readout of an artificial spin: the transmon qubit. They use advanced experimental tools, including a dilution refrigerator (20 mK), microwave equipment (amplifiers, attenuators, circulators…), a vector network analyzer, microwave sources, and a Zynq UltraScale+ RFSoC ZCU216 for fast readout and pulse generation. The sample consists of a microwave readout cavity dispersively coupled to a transmon qubit in a planar geometry.
Throughout the lab work, students perform qubit spectroscopy and learn how to manipulate it. Standard experiments include Rabi oscillation measurements, Ramsey fringes, and the determination of relaxation and decoherence times.
A unique hands-on experience at the forefront of quantum technologies!
