Theoretical Quantum Optics

We are the newly established Theoretical Quantum Optics (TQO) group at the Institute for Atomic and Subatomic Physics (Atominstitut) of TU Wien, a part of the Quantum Optics and Quantum Information research area.

Recent years have seen great advances in the ability to engineer, control, and measure correlated quantum states using quantum fields and optical elements. Our group is interested in exploring quantum information processing protocols and investigating fundamental aspects of quantum mechanics within the quantum-optical setting by exploiting these novel tools.

By linking quantum optics and quantum information, we aim to understand quantum-correlated fields and few-body quantum systems, mainly composed of single atoms and photons. We investigate both infinite and finite dimensional quantum systems (continuous- and discrete-variable) and are particularly interested in hybrid-dimensional scenarios. These scenarios interface different physical components with complementary functionalities, achieving efficient storage, processing, and transmission of quantum information.

Focusing on experimentally friendly criteria, we study the quantum theory of measurements to further understand fundamental aspects of nature. Additionally, we explore their applications in quantum technologies, which promise novel uses beyond those achievable with classical resources.
