Published in Quantum: Identifying Pauli spin blockade using deep learning

Pauli spin blockade (PSB) can be employed as a great resource for spin qubit initialisation and readout even at elevated temperatures but it can be difficult to identify. In this paper, we present a machine learning algorithm capable of…

Published: Charge sensing of a Ge/Si core/shell nanowire double quantum dot using a high-impedance superconducting resonator

Hole spin qubits in Ge/Si core/shell nanowires are promising candidates for scalable quantum information processing. Here, we employ a high-impedance, magnetic field resilient superconducting microwave resonator based on a NbTiN thin-film…

Published in Physical Review Research: Measurement-induced population switching

The act of measurement in quantum mechanics imparts backaction and fundamentally impacts the measured object. In this work, we show how increasing the bias on the charge sensor (pink) changes the charge stability diagram of the double dot…
