Quantum algorithms, metrology, and sensing under real-world constraints.
We develop protocols that stay effective where ideal theory breaks down — under noise, finite measurement data, and limited control. Our work spans quantum estimation theory, variational algorithms, and quantum-enhanced sensing, from foundations through to implementations on near-term devices.
Research
All research areas →
Quantum metrology & sensing
Quantum-enhanced protocols that exploit entanglement, squeezing, and optimal control to reach precision beyond classical limits — including time-dependent strategies and networked sensors robust to realistic noise.
Read more →
Quantum algorithms & compilation
Device-aware variational and feedback-based methods — VQE, variational compilation, exact gradients, and FALQON-style control — designed to remain practical under limited circuit depth and hardware noise.

Entanglement & measurement
Practical methods to detect, certify, and protect entanglement on noisy devices: nonlocality tests, variational entanglement witnesses, and optimized measurement strategies for multipartite systems.
Foundations & nonlocality
Quantum correlations beyond classical hidden-variable models, studied in multipartite systems and quantum networks — connecting foundational questions to verification and communication protocols.
