AWhat changed
Anderegg and colleagues loaded individual calcium monofluoride molecules into five optical tweezers and used fluorescence to identify occupied sites. In the reported setup, the average loading probability was about 34% per trap; the authors obtained 92% detection fidelity under optimized imaging conditions. The team also studied loss associated with collisions.
Scientific scope
Anderegg and colleagues loaded individual calcium monofluoride molecules into five optical tweezers and used fluorescence to identify occupied sites. In the reported setup, the average loading probability was about 34% per trap; the authors obtained 92% detection fidelity under optimized imaging conditions. The team also studied loss associated with collisions. Loading was stochastic, and detection fidelity is not the same as loading probability. The experiment did not demonstrate a defect-free rearranged array or a molecular quantum gate. Collision rates depend on estimates and the measured loss channels were not uniquely identified.
