A New Light for Quantum Sensing

Since March 1, 2026, Dr. Vira Besaga is leading the “Quantum and Hybrid Light” junior research group at the Institute of Applied Physics (IAP) at Friedrich Schiller University Jena. As part of the Nano & Quantum Optics research group, she is investigating new concepts of quantum and hybrid light for future photonic quantum technologies.

Scientific ways

Her scientific career began with a bachelor’s degree in optics, with the engineering component being a very deliberate choice: “I am very interested in applications. It is important to me that research contributes to solutions with a clear purpose and measurable impact.”

Dr. Besaga consistently pursued this path, from her master’s degree with a focus on photonics to her Ph.D. at Ruhr University Bochum in 2020 in the field of digital holographic metrology. As a postdoc, she focused on quantum optics: “I wanted to challenge myself by entering a new field, learning about different approaches, and broadening my scientific perspective.”

Current interests

In her current research, Dr. Besaga combines classical optical methods with quantum optical approaches. She is investigating hybrid photonic states that combine quantum resources with the structural and topological properties of light. A central focus of this research is quantum-enhanced sensing. To achieve this, non-classical correlations are used to increase measurement accuracy beyond classical limits, while specifically designed topological properties of light help preserve information during propagation and up to detection.

Jena by Choice

Dr. Vira Besaga hopes to bring this ambitious project to life here in Jena: “Jena combines a remarkable scientific heritage with a strong spirit of innovation. The environment of highly motivated researchers creates an inspiring atmosphere that continually stimulates growth.” In particular, she values the local research infrastructure, the administrative support, and the collaborative culture, which enable the rapid development of new ideas. “Here you find both academic freedom and a vibrant environment where nature, culture, and a strong academic community come together,” says Dr. Besaga.
