Quantum Physicist Specializing in NV-Center Quantum Sensing, Optimal Control, Microwave Engineering, and Simulation

Profile Summary

I am a quantum physicist with a strong background in both theoretical and experimental research. Currently pursuing a Ph.D. in the Quantum Spin Dynamics Lab at University College London, I am working under the guidance of Prof. John Morton. My research focuses on quantum sensing using optically active spin defects, with a state-of-the-art confocal microscopy setup integrated with an air-cooled cryostat. My work has included assembling precision optical and electronic systems, developing Python code for fully automated experimental setups, and optimisation of spin properties of NV centers. These projects highlight my ability to bridge hardware integration and software development for cutting-edge quantum experiments. Research Experience Ph.D. Research: Specializing in sub-nanometer precision quantum sensing and optically active spin defects. Developed fully automated confocal microscopy setups and performed advanced spin characterization of NV centers, including their use in atomic force microscopy. Quantum Optimal Control in NMR: Designed robust radio-frequency pulses using the GRAPE technique, implemented on multi-qubit systems, and developed innovative pulse sequences for pseudo-pure state generation. Ultrafast Time Synchronization: Conducted experiments integrating ultrafast time synchronization using microwave and optical systems, advancing quantum control precision. Skills and Tools Quantum technologies: NV centers, NMR, ultrafast time synchronization Quantum control theory and optimization (GRAPE, pulse sequences) Hardware-software integration for experimental setups Python programming for automation and data analysis Software tools: COMSOL, CST, MATLAB, Mathematica, Dip Trace Data modeling, signal processing, and numerical simulations Publications Co-author of "Stability of near-surface nitrogen vacancy centers using dielectric surface passivation" (ACS Photonics, 2024). Collaborated on multiple research manuscripts, including studies on NV centers and their applications in quantum sensing. Career Goals I aim to push the boundaries of quantum technologies, particularly in sensing and computation, by integrating robust quantum control techniques with advanced experimental setups. My passion lies in multidisciplinary collaborations that translate fundamental physics into real-world quantum innovations.
