Abstract
Reading a molecule without destroying it
Achieving efficient quantum control of ultracold molecular systems may open opportunities in molecular precision spectroscopy, quantum information, and related fields. Sinhal
et al.
report a quantumnondemolition protocol for the detection of the spin-rovibronic state of a single trapped cold molecular ion co-trapped with an atomic ion. They show that monitoring the motion of Ca
+
after coherent motional excitation of the Ca
+
-N
2
+
string makes it possible to detect the N
2
+
state without destroying either the molecule or the state itself. The procedure can be repeated multiple times while preserving the high readout fidelity.
