Area of Expertise

I am a UK Quantum Technologies Research Fellow and have worked in theoretical quantum optics, information, and communications. I obtained my PhD from the University of Sheffield and an MSci in Physics from Imperial College London. I currently work at the interface of finite and one-shot quantum information theory. Specifically, I am currently working on developing novel schemes that determine optimal experimental implementations for enhanced sensing and satellite-based quantum communications over long distances, where finite statistics naturally arise owing to finite quantum channels between satellites and optical ground stations. 

I work closely with experimentalists and engineers to model and guide the design of upcoming satellite quantum key distribution missions, including the UK Quantum Communications Hub mission, QUARC/ROKS, and the Canadian QEYSSat mission. My work is primarily steered by practical designs and constraints, involving a range of numerical techniques for computational modelling and theoretical work on security analyses.

Qualifications

I have been heavily involved in teaching at varying capacities and have been accredited as a Fellow of the Higher Education Academy.

I also work heavily on outreach programmes to break down complex concepts and communicate them effectively to the public. I have spoken at secondary schools to motivate and engage students in the potential of quantum technologies and led the development of animation to highlight the importance of satellite quantum communications, which featured in the UK National Quantum Technologies Showcase and the UK Quantum Communications Hub website.

I am the Science Faculty Representative to the public engagement at the University of Strathclyde and have been working to implement strategic goals towards the university's ambitious 2025 Vision.

Research Interests

My research interest is at the intersection of quantum information theory and practical devices that can be implemented. I have worked on:

1. understanding and developing finite key analyses for quantum key distribution,

2. developing efficient routing protocols for quantum resources towards a long-term quantum internet through distributed technologies,

3. determining fundamental precision limits for quantum metrology and sensing,

4. working towards practical quantum receivers that can be implemented in the laboratory and can outperform existing receivers.

I am also interested in researching how methods in quantum computing can be used to provide robust quantum estimation procedures.

SUPA Visit funding for research collaboration with Italy
Sidhu, Jasminder (Principal Investigator)
Competitively awarded funding from the SUPA awarding body of £2500. The primary aim of this research visit was to understand the engineering difficulties in developing satellites for global quantum communications, and the fundamental questions that need addressing to improve the performance of SatQKD systems. The group of Profs. Vallone and Villoresi at the University of Padova and the Italian Space Agency are experts in the field to address and understand these questions. This SUPA-supported research visit enabled me to visit these different research groups in Italy to understand the growing efforts in quantum technologies and establish new collaborations.
