Qubit Design and Measurements (QDM)
Irinel Chiorescu | Kenneth Hanson | Stephen Hill | Michael Shatruk | Komalavalli Thirunavukkuarasu
This research theme focuses on the bottom-up synthesis of molecular spin qubits, as well as linking them to form dimers, trimers, etc., that can mimic simple quantum logic gates. These efforts are complemented by studies of coherence in diluted spin systems and advanced measurements, such as X-ray diffraction, electron paramagnetic resonance, optical spectroscopy, and on-chip detection both to provide feedback for the synthetic effort and to demonstrate key quantum properties such as entanglement.

Quantum and Topological Materials (QTM)
Luis Balicas | Christianne Beekman | Shalinee Chikara | Guangxin Ni | Laura Greene | Dragana Popovic | Geoffrey Strouse | Kaya Wei | Peng Xiong | Wan Kyu Park
This research theme encompasses studies of materials and devices exhibiting novel quantum electronic and magnetic properties that result from dimensional confinement, electronic correlation, spatial symmetry, and nontrivial band topology. The goals are both to elucidate the fundamental physics underlying the unusual quantum phenomena and to harness them for quantum sensing, memory, and computation applications.
