Connecting Quantum Platforms: Photons, Entanglement, and India–Austria Opportunities in Quantum Science

Talk

Photons and entanglement have played a central role in shaping our understanding of quantum foundations, and they are now becoming key ingredients in emerging quantum technologies. In this talk, I will discuss how photonic quantum systems are moving from controlled laboratory demonstrations toward deployable quantum infrastructure for communication, certification, sensing, and networked quantum information processing.

I will present selected directions in entangled-photon experiments, quantum communication, and field-oriented quantum technologies, emphasizing the scientific questions that arise when quantum systems must operate across distance, platforms, and realistic environments. A particular focus will be on photons as natural interfaces between diverse quantum systems, including atoms, solid-state emitters, memories, superconducting devices, and many-body platforms.

In the context of growing India–Austria scientific engagement, I will outline how complementary strengths in photonics, quantum optics, theory, metrology, and hybrid quantum systems can open collaborative routes toward both fundamental tests of quantum mechanics and scalable quantum technologies.
