Congratulations to Daniel Halverson on winning a $15,000 CSIRO Honours scholarship to undertake a project on hole spin qubits in the QED group with Dr. Scott Liles and Prof. Alex Hamilton

Just published in Nano Letters: Dr. Feixiang Xiang, PhD student Abhay Gupta, and a great team of national & international collaborators report new and unexpected behaviour of quantum Hall states in bilayer graphene when large gate biases are applied. pubs.acs.org/doi/10.1021/acs…
Matt and Scott’s latest paper on transverse magnetic focussing is out now on the arXiv (arxiv.org/abs/2310.04005). We use focussing to probe a section of the Fermi surface and observe non-adiabatic spin dynamics and a high sensitivity to spin dependent scattering.
QED's Abhay Gupta attended the 2D Quantum Matter Summer School in Lucca, Italy in July.
His poster titled – "Theoretical modelling on new level crossings and electron-hole asymmetry in Landau Octet of bilayer graphene" was awarded one of the 3 top posters!

QED loved having Juan Salvador Sánchez, a visiting PhD student from the Nanotechnology group at Universidad de Salamanca here working with the team. He and Abhay Gupta and working on a graphene hydrodynamics project - Graphene Traffic Merge Control Equipment. @UNSWScience @usal
Amazing to see a quantum device go from an idea on a whiteboard to a real physical sample, in the skilled hands of Dr. Yonatan Ashlea-Alava. Gotta love ANFF’s new direct write lithography system…

Congratulations to @AaquibShamim , winner of the $500 People’s Choice Award, for garnering the most votes from @SydneyQuantum Australia attendees for his poster Pauli Spin Blockade and g-factor Anisotropy in Hole Si CMOS Double Quantum Dot.

Our work with Diraq on Si CMOS hole double quantum dot was presented at SQA Conference by @AaquibShamim . We investigated the hole g-factor anisotropy and g-factor difference between the two quantum dots, which can be used to perform coherent spin manipulation in a qubit.

Gordon Godfrey Workshop 2022 on "Spins, Topology and Strong Electron Correlations" has wrapped up. Great to be back together for this theoretical workshop, with strong participation from leading experimentalists – domestic and international @UNSWScience @FLEETCentre @UNSWScience
Another paper out on the ARXIV - All is not what it seems: Our preprint investigating spin dependent magnetic focussing in holes, showing a new understanding of apparent spin polarisation signals, is now on the server arxiv.org/abs/2210.03383 @RendellMatthew

Our @FLEETCentre @SydneyQuantum study of how the orientation of hole devices on a wafer has a huge effect on their spin properties is now on the preprint server - a really nice combination of experiment and theory to find new terms in the Hamiltonian arxiv.org/abs/2211.00253

Our work with Andrew Dzurak's @UNSWEngineering team combining electron sensors and hole quantum dots for spin qubits has gone up on the arxiv arxiv.org/abs/2211.00178

It was good to hear Dr Feixiang Xiang’s latest research findings; Dr Xiang’s research focuses on topological and strongly correlated physics in two-dimensional materials for low-energy electronics.
