  Understanding chiral induced spin-selectivity (CISS), resulting from charge
transport through helical systems, has recently inspired many experimental and
theoretical efforts, but is still object of intense debate. In order to assess
the nature of CISS, we propose to focus on electron-transfer processes
occurring at the single-molecule level. We design simple magnetic resonance
experiments, exploiting a qubit as a highly sensitive and coherent magnetic
sensor, to provide clear signatures of the acceptor polarization. Moreover, we
show that information could even be obtained from time-resolved electron
paramagnetic resonance experiments on a randomly-oriented solution of
molecules. The proposed experiments will unveil the role of chiral linkers in
electron-transfer and could also be exploited for quantum computing
applications.
