Entanglement Certification

Fri, 18 Sep 2026 00:00:00 +0000

How can entanglement be certified without reconstructing a complete quantum state? This research combines mathematical criteria based on positive maps and invariants with experimentally accessible randomized measurements. The aim is to obtain rigorous guarantees that remain useful with finite data, noise, and restricted measurement access.

Secure Quantum Communication

Fri, 18 Sep 2026 00:00:00 +0000

This theme studies how security guarantees change when quantum communication protocols use finite data, imperfect devices, and realistic noise models. It includes device-independent QKD, finite-size proof techniques, and discrete- and continuous-variable protocols.

Quantum Foundations and Self-Testing

Thu, 17 Sep 2026 00:00:00 +0000

Bell inequalities and contextuality provide operational tests of nonclassical behaviour. This work develops such tests into practical certification tools, including self-testing protocols that identify quantum states and measurements from observed correlations.

Protection of Quantum Information

Wed, 16 Sep 2026 00:00:00 +0000

Quantum information is fragile. This research develops probabilistic and resource-aware methods that filter or mitigate errors while retaining useful quantum information for communication, computation, and sensing.

Quantum Optics and Imaging

Tue, 15 Sep 2026 00:00:00 +0000

This line of work studies how correlations in light improve imaging and sensing, and how the spatial structure of quantum emitters changes their interaction with electromagnetic environments.

Quantum Machine Learning

Mon, 14 Sep 2026 00:00:00 +0000

This research investigates when quantum-data kernels remain informative with finite measurement budgets, with emphasis on resource scaling, concentration effects, and quantum phase-transition learning.
