Description
Many beyond-the-Standard Model theories predict that the fundamental constants may change in time and space. Potential changes in one of those constants, the proton-to-electron mass ratio μ, can be detected by comparing vibrational or rotational transitions in molecules to optical transitions in atoms. In our experiment, a vibrational transition in N$_2^+$ will be compared to atomic clocks within the QSNET network of quantum sensors [1]. The nitrogen ion will be co-trapped in a linear Paul trap with an auxiliary $^{40}$Ca$^+$ ion which will be used for ground state cooling and state detection via a quantum logic scheme. I will report on our recent progress on the experiment.
