Trapped Rydberg atoms have been used as viable systems to study collective phenomena in many-body physics owing to strong long-range interatomic interactions and an extraordinary long lifetime of Rydberg states. They have been recognized as an effective platform to simulate interacting spin systems and to understand many-body quantum properties, such as quantum magnetism and nonlocal correlations. The ability to generate entangled states on demand is paramount to modern quantum-enabled technology. In this project, a methodology is proposed to create the Greenberger-Horne-Zeilinger (GHZ) and the W multipartite entangled states on the manifold of the ground and Rydberg states of trapped alkali atoms. The methodology is based on the two-photon adiabatic passage using linearly chirped pulses, with the Rabi frequencies overlapping to perform excitations within adiabatic regime. It is assumed for a generation of entangled states of different classes in various configurations of atoms, e.g., spin chains and arrays. While quantum optimization algorithms are beneficial for large systems with vanishing spectral gaps, our analytical method is more practical for systems of tens of atoms.

We propose a novel approach for remote detection of hazardous contaminants. It is based on quantum-enabled coherent anti-Stokes Raman scattering (CARS) of laser radiation from distant molecules in the backward direction. The quantum enhancement is achieved by implementing a quantum control methodology which maximizes quantum coherence in the target molecules. The detection principle relies on a nonlinear optical response of the target molecules with a blue-shifted radiation generated coherently in the direction defined by the phase-matching condition in the four-wave mixing of CARS. The conguration of the laser beams implies the box scheme, with the anti-Stokes signal emerging from the fourth corner. It will be implemented on a multi-static platform such as nearby inflatables or unmanned aerial vehicles (drones). We assume a significant enhancement of the signal using quantum control approach within this laser conguration on the multi-static platform.

The ability to manipulate and to control individual quantum systems enables novel technologies and new ways to study our Universe. In this theory group we use tools from quantum optics and quantum information theory to explore quantum phenomena in new regimes, especially at the interface with gravity. Focusing on capabilities of novel quantum systems that are experimentally accessible, our goals are to explore new applications for quantum technologies, to better understand the strengths and limitations of quantum theory and to show how the interplay between general relativity and quantum mechanics can be experimentally tested.

Topological states of quantum matter, protected by symmetry and characterized by nonlocal quantum correlation, are particularly robust against local distortions that inevitably occur in experiments. In this project, we will engineer and investigate topological states in various controllable quantum systems such as ultracold atoms and optical materials. Topological quantum matter offers a promising platform for intrinsically stable quantum computation and information processing.

The main focus of this project is to understand the properties of quantum many-body systems with strong interaction between constitute particles. The interplay of long-range interaction, external driving, disorder, and dissipation will be explored, and the build-up of quantum correlation will be characterized and controlled. The results will advance our understanding of many-body quantum systems and are expected to have a wide range of applications in quantum metrology and quantum information science.
