Boskovic is a synthetic inorganic chemist working on lanthanoid and polyoxometalate molecular magnets, valence tautomeric and redox-switchable complexes, and the design of molecules whose spin states can be addressed and switched. The group's relevance to quantum sensing is that these are chemically tunable spin qubits: unlike solid-state defects, their coordination environment, nuclear-spin bath and anisotropy can be designed atom by atom, which is the argument for molecular qubits as sensors. Characterisation is by SQUID magnetometry, EPR and ab initio calculation. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — molecular spin qubits are the chemistry community's answer to the NV centre, and DEER/pulsed-EPR protocols developed for NV ensembles at pT/sqrt(Hz) transfer more or less directly to these systems. Borderline inclusion (synthesis-led rather than sensitivity-led), kept per the inclusive rubric.

Roessler uses continuous-wave and pulsed EPR/ENDOR spectroscopy to probe paramagnetic metal centres and radical intermediates in catalytic and bioinorganic systems, work that overlaps with the use of molecular spin centres as candidate EPR-addressable qubits/sensors.
