Description
We implement a single electron charge qubit in a gate defined linear triple dot array on a GaAs/AlGaAs heterostructure [1,2]. The qubit is strongly dipole-coupled to photons in a high impedance frequency tunable superconducting resonator. We operate the qubit at a higher order sweet spot along one of the detuning axes. Measuring the qubit coherence for different qubit configurations we acquire information about the dominant noise source in our system.
