Machine learning has been the enabler of well-known breakthroughs in computer science, such as the victory of Alpha Go over a Go world champion and superhuman face recognition. We can direct this potential to the characterisation and tuning of quantum devices in real time. As in Go, where a player must carefully balance short and long-term goals and devise actions accordingly, we have...

8. Transmission based qubit noise spectroscopy

Noise spectroscopy is an important first step towards mitigating the detrimental effects of noise on qubits. In this talk I will speak about the transient and long-time transmission through a resonator containing a generic noisy qubit and show that characteristic features of the noise are imprinted in the fluctuations of the averaged resonator response. I will present analytical expressions...

7. Correlated charge noise in Si/SiGe quantum dot spin qubits

Electron spin qubits in silicon quantum dots are particularly promising candidates for the implementation of a large-scale quantum computer due to their small physical footprint. However, this compactness raises concerns on the existence of spatial noise correlations that can be severely detrimental for quantum error correction. In this talk, I will show our results on noise spectroscopy of...
