I am a senior scientist and investigator at the Agency for Science, Technology and Research, Singapore, a visiting faculty member at Centre for Quantum Engineering, Research and Education, India, and an editor at the community-run Quantum journal. My research interests are diverse, covering areas such as quantum device certification, quantum machine learning, quantum error correction, quantum complexity theory, near-term quantum computing, and pseudorandomness. Through my research, I try to develop protocols for certification and benchmarking of third-party quantum devices that are accessible via cloud, under minimal assumptions. Additionally, my work seeks to pinpoint particular applications where quantum devices have the potential to outperform classical systems. I am interested in both practical and rigorous protocols that can showcase this quantum advantage. A key part of my research is to understand the impact of noise on the performance of quantum systems and to quantify the extent of quantum advantage that can be achieved despite this noise. I also focus on developing strategies to mitigate noise with limited resources.
