Projects

This is a list of projects I worked on previously, currently covering the time span from undergraduate years to the end of my DPhil. It is by no means complete, and the durations of the projects span orders of magnitudes.

DPhil, 2022–2026

The most comprehensive description of this section is of course well documented in the long PDF which every PhD student needs to write when they finish up. This will be soon available, but for now you can find a brief overview here.

• 2022–2026

  Ion trap development

  I built a new ion trap system from the ground up. This includes the assembly of the trap, the optics, and the control electronics. Wondering what an ion trap is? Read the article!

• 2025–2026

  Coherent operations

  I demonstrated coherent control of the quantum state of the ion in the system I built, by implementing the core routines of resolved sideband cooling, Rabi flops, and Ramsey interferometry.

• 2022–2026

  Modular quantum computing

  I developed and tested technologies to be integrated in a prototype node for an ion trap quantum network with photonic interconnects.

• 2024–2026

  Numerical simulationsJulia

  I developed a Julia package to simulate laser-ion coupling strengths and laser-Hamiltonian interactions. The package is available on the group's GitHub.

• 2023–2024

  Laboratory monitoring

  Tracking temperature and pressure drifts in a lab is important when debugging problems. I built a low-cost (<£100) modular environmental logging system using Raspberry Pis and a custom PCB which mounts as a "hat". The PCB interfaces with off-the-shelf consumer-electronics sensors.

• 2022–2023

  Laser systems

  Large and drifty laser systems are a challenge for scalable and reliable laser-based quantum computers. I built a stable rack-mounted laser system to control four strontium ion-trap experiment. Its footprint is less than $0.5\ \text{m}^{2}$.

• 2022–2023

  Vacuum systems

  I assembled a pump station for ultra-high-vacuum applications. The station integrates backing, turbo and ion pumps, and monitoring diagnostics such as a pressure gauge and a residual gas analyser.

Physics and maths

Projects from my MSci at Imperial College.

• 2022

  Quantum Machine LearningPythonPyTorchPennyLane

  Submission for a hackathon on quantum computing. We developed a quantum hybrid neural network.

• 2021–2022

  Quantum Chaos with RBMPythonQuTiP

  Master project investigating quantum chaos using Restricted Boltzmann Machines (RBM).

• 2021

  AI HackathonPythonTensorFlow

  I applied CNNs to the prediction of crop yield. Together with my team we won the first prize in our category.

• 2021

  Barabási-Albert NetworkPython

  I investigated the degree distribution for random attachment and preferential attachment networks both theoretically and computationally.

• 2021

  Oslo ModelPython

  I investigated the Oslo rice-pile model, which is an example of Self-Organised Criticality (SOC).

• 2020

  Thermal SimulationPython

  I solved the steady state heat PDE to simulate a microprocessor using numerical methods.

• 2020

  Fresnel SimulationPython

  Investigated the Point Spread Functions of an Oblique Plane Microscope using a scalar light field model.

Hardware

Electronics projects from my MSci.

• 2021

  Pulse OximeterAssembly

  I built a pulse oximeter using a PIC18F87K22 microprocessor by Microchip Technology. I wrote the code in Assembly with my lab partner (check the repo).

• 2019

  Fluxgate MagnetometerArduino

  I built a fluxgate magnetometer sensor from scratch. The readings were collected with a readout circuit and output on an LCD with an Arduino board.

Software

• 2021

  Flutter AppDartFlutter

  I worked on a Flutter application. The software interacted with a Bluetooth server hosted on a Raspberry Pi to configure its wifi settings. Based on the flutter_reactive_ble library.
