Congratulations Suraj!

sophiengineer

A congratulations is in order for our group member Suraj Goel!

Suraj gave talks at the SPIE Photonics Europe and SPIE Optical Systems Design 2024 conferences in Strasbourg, presenting our work on reconfigurable quantum optical circuits, and multi-plane neural networks at each conference respectively.

He won the best paper award (2nd Place) at computational optics session for his talk on “Characterization of scattering systems using multi-plane neural networks“. We are very proud of him and the only thing left to ask is what will he spend his prize money on!?

Arxiv: A dynamical model of quantum measurements

sophiengineer

We are happy to announce our most recent arXiv submission: Equilibration of objective observables in a dynamical model of quantum measurements (https://arxiv.org/abs/2403.18016). There are many unanswered questions when it comes to quantum measurements. One such question: how can something seemingly irreversible, like a measurement, arise from unitary (and therefore reversible) dynamics? We find that the answer lies in quantum thermodynamics and the idea of equilibration-on-average!

In this paper, we work within the framework of the Measurement Equilibration Hypothesis (MEH) to construct a set of objectifying observables, best at objectively encoding the measurement statistics of a system. Our work has foundational implications for the emergence of classicality, as well as providing a step towards a fully physical model of quantum measurements. This work was carried out in collaboration with Dr. Max Lock and Dr. Tom Rivlin from the Quantum Information and Thermodynamics group (QuIT Physics) at TU Wien.

Sophie @ Quantum Morocco

Sophie attended Quantum Morocco 2023 in the capital city of Rabat. It is a beautiful and relaxed city, with amazing food, surfing and plenty of cats! Despite the devastating earthquake in the Marrakesh area, the conference organizers decided to proceed with the event. This decision was a testament to the resilience and strength of the Moroccan people. Their hospitality in the face of such a tragic event was inspiring. The conference had a diverse range of talks on topics such as quantum information theory, quantum metrology, quantum machine learning, and even flight optimization. Sophie presented her work modelling quantum measurements as a thermodynamic process. Keep an eye out for Quantum Morocco 2024!

Welcome Dylan!

sophiengineer

Dylan is joining us after completing two successful undergraduate projects with the group. He completed his physics degree at Heriot-Watt and his final year dissertation foccussed on controlling quantum states in space and time in a multi-mode fibre. He has plenty of experience in the lab as well as with computational simulations!

We warmly welcome you to BBQLab!
