Kamal directs the QUEST (QUantum Engineering Science and Technology) group, developing theory for quantum-limited readout of superconducting circuits: nonreciprocal parametric (Josephson-junction) amplifiers, left-handed-metamaterial traveling-wave amplifiers, and autonomous entanglement stabilization/error-correction protocols. Her work sets the fundamental noise limits that superconducting-qubit-based quantum sensors and quantum computers can approach, in close collaboration with experimental groups at NIST Boulder and elsewhere. The group is actively recruiting postdoctoral scholars.
Kasevich is a pioneer of light-pulse atom interferometry, building cold-atom sensors of rotation, acceleration, and gravity that rival or exceed classical inertial instruments, and precision tests of general relativity and searches for dark matter and gravitational waves via large-scale atom interferometers (including MAGIS-100). His 2022 Nature paper demonstrated distributed quantum sensing with mode-entangled, spin-squeezed atomic states, extending entanglement-enhanced metrology to networks of separated sensors.
Kassal is the leading Australian theorist of quantum effects in light harvesting. He established the distinction between coherent processes and coherent states in photosynthesis β showing that under incoherent sunlight at steady state, wavelike motion per se does not enhance efficiency, while environment-assisted transport and supertransfer genuinely can β and has since developed a classification of the mechanisms by which coherence (excitonic, vibrational, or of the light field itself) can improve energy transport. He also pioneered quantum-computer algorithms for chemistry. A distinct and directly relevant thread is the theory of spectroscopy with non-classical light: what entangled or squeezed photons can reveal about molecular coherence that classical light cannot. Positioned against the established body of NV-ensemble quantum sensing work β DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity β his work is the theoretical counterpart to the quantum-biology ambitions of the NV community: where NV ensembles at pT/sqrt(Hz) try to detect the magnetic signatures of biological spin chemistry, Kassal asks what quantum coherence is actually doing in those systems and whether quantum light can interrogate it.
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.

Kocharovskaya is a theorist (with supporting experiment) in coherent optics: EIT, lasing without inversion, and X-ray/gamma quantum optics using nuclear coherent control (Moessbauer nuclei) for ultra-narrowband photon storage and precision spectroscopy. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work provides coherent-control primitives relevant to precision sensing.
