Quantar Lab

We develop efficient, device-aware quantum algorithms for near-term quantum computers, with a strong focus on variational methods such as VQE, variational quantum compilation, variational quantum metrology, and feedback-based optimization frameworks including FALQON. Our goal is to design practical quantum workflows that can be implemented on realistic hardware while remaining robust against noise and limited circuit depth. These algorithmic tools are applied to a wide range of problems, including many-body physics simulation, quantum sensing and metrology, combinatorial optimization, and emerging applications such as molecular modeling and drug discovery.

Quantum Entanglement & Measurement

We investigate quantum entanglement and measurement as fundamental resources for quantum technologies. Our research focuses on practical methods to detect, certify, and protect entanglement in realistic noisy devices, including nonlocality tests, variational entanglement witnessing, and optimized measurement strategies. We also study measurement-induced phenomena and their applications in quantum communication, quantum sensing, and scalable verification protocols for multipartite quantum systems.

Quantum Metrology & Sensing

We develop quantum-enhanced metrology and sensing protocols that exploit entanglement, squeezing, and optimal control to achieve precision beyond classical limits. Our research focuses on time-dependent sensing strategies and networked quantum sensors, aiming to improve robustness against realistic noise and experimental imperfections. These methods provide a foundation for next-generation technologies in weak-signal detection, spectroscopy, and precision measurements in fundamental physics.

Quantum Foundations & Nonlocality

We explore the fundamental principles of quantum mechanics through nonlocality, entanglement, and measurement theory. Our research focuses on identifying quantum correlations that cannot be explained by classical hidden-variable models, including multipartite systems and quantum networks. By developing practical, device-friendly protocols for testing nonlocality and certifying quantum resources, we aim to connect foundational physics with emerging applications in quantum communication, sensing, and verification.
