Anders Sørensen's Theoretical Quantum Optics group develops theories for controlling individual quantum systems (atoms, photons, solid-state emitters) with focus on quantum information processing and communication. Research includes protocols for quantum repeaters, quantum networks, optomechanical systems, and transduction between microwave and optical frequencies. Strong collaboration with experimental groups at NBI and internationally; core member of the Hy-Q centre.
Stamper-Kurn's group uses site-resolved quantum-gas microscopy and cavity optomechanics with ultracold atoms to study strongly correlated many-body quantum matter and quantum measurement backaction, techniques that double as some of the most sensitive atom-based force and field sensors available.
Gary Steele's lab works on quantum circuits and mechanical quantum systems, exploring quantum phenomena in nanoelectromechanical (NEMS) and superconducting circuit systems.

The group develops novel quantum sensors for mechanical forces and electromagnetic fields.
The Stern Group explores fundamental quantum interactions of photons with 2D materials, nano-scale structures, and atoms. Key thrusts: (1) Valley-selective exciton-polaritons in monolayer transition-metal dichalcogenides (MoS₂, MoSe₂, WSe₂) embedded in optical microcavities — hybrid light-matter quasiparticles with valley-selective polarization and cavity-modified dynamics; (2) 2D semiconductor quantum emitters — quantum-dot-like single-photon emitters formed by confinement in TMD nanoribbons and by chemical functionalization/strain engineering of defects; (3) Astrophotonics: collaboration with Argonne National Laboratory and the Australian Astronomical Observatory to design and fabricate silicon ring-resonator photonic circuits for OH sky-background suppression in near-IR astronomical spectrographs; (4) Quantum non-reciprocal photonics in axisymmetric microresonators. Experimental tools: time-resolved spectroscopy, single-photon counting, nanofabrication. DOE Early Career Award; ONR Young Investigator Award; Sloan Research Fellow 2013. Affiliated with Fermilab-Northwestern CAPST.
Suleymanzade builds hybrid quantum systems that couple Rydberg atoms, superconducting circuits, and nanophotonics to create new quantum interfaces and entanglement resources for quantum networking, communication, and sensing, following earlier work on silicon-vacancy diamond quantum networks.
