In this work, we demonstrate the quantum control and precision spectroscopy of a clock transition in a single molecular nitrogen ion. We report the first observation of Rabi oscillations and spectra on a mid-infrared electric-quadrupole rovibrational transition in a molecular ion, thus establishing a robust platform for the coherent manipulation of high-fidelity molecular qubits and clock...

H$_2^+$ is the simplest molecular system, and its energy-level structure can now be calculated at the parts-per-trillion level[1]. Comparing experimental and theoretical transition frequencies enables the improvement of the value of fundamental constants, such as the proton-to-electron mass ratio $\frac{m_p}{m_e}$[2].

An increased sensitivity to $\frac{m_p}{m_e}$ can be obtained when...

Long Talk (20min)

Quantum logic spectroscopy (QLS) has been established as a versatile technique for high-precision spectroscopic studies of diatomic molecular ions co-trapped with atomic ions in an ion trap, contributing to fundamental physics research and quantum information applications [1-6]. However, extending this protocol to larger polyatomic molecular species is challenging due to their more complex...

Short Talk (15min)

Radioactive molecules provide an incredible $10^{12}$-fold boost in precision for measuring parity violation in the nuclear weak force [1]. Realizing this potential requires accurate rotational spectroscopy to locate, assign, and control the relevant quantum states. Moreover, the rotational transitions of heavy, short-lived molecules lie in the microwave-to-radio domain, providing a powerful,...
