Kim's theoretical group works on quantum optics and quantum information, including generation and application of non-classical light (cat states, GKP states) for quantum metrology, continuous-variable quantum information and fundamental tests of quantum mechanics.

Pioneer of experimental quantum optics with entangled and hyper-entangled photons; research spans quantum information processing, quantum communication, quantum-enhanced metrology and sensing, and fundamental tests of quantum mechanics using single- and entangled-photon sources.

Lvovsky works broadly across quantum and optical technology, from foundational quantum optics (non-classical light states) to quantum-enhanced imaging; recent work combines spatial-mode demultiplexing with image scanning microscopy to push lateral resolution beyond the classical diffraction limit.

Mintert's theoretical group works on quantum information and quantum control, including protocols to deterministically prepare highly non-classical (non-Gaussian, Wigner-negative) states of massive mechanical oscillators via optomechanical interactions, entanglement quantification, and quantum simulation.

Studies neutral-atom quantum computing and quantum optics with Rydberg atoms in optical tweezer arrays, including entanglement, nonlinear optics, and Rydberg-based electrometry/sensing.
