• Abstract: Frequency up-conversion, enabled by molecular optomechanical coupling, has recently emerged as a promising approach for converting infrared signals into the visible range through quantum coherent conversion of signals. However, detecting these converted signals poses a significant challenge due to their inherently weak signal intensity. In this work, we propose an amplification mechanism capable of enhancing the signal intensity by a factor of 1000 or more for the frequency up-converted infrared signal in a molecular optomechanical system. The mechanism takes advantage of the strong coupling enhancement with molecular collective mode and Stokes sideband pump. This work demonstrates a feasible approach for up-converting infrared signals to the visible range.

• Universal and robust dynamic decoupling controls for zero-field magnetometry by using molecular clock sensors [0.0]
  Color centers in diamond and silicon carbide (SiC) and molecular spins through a host matrix control are promising for nanoscale quantum sensing. However, large transverse zero-field splitting (ZFS) is often inevitable due to their intrinsic symmetry and/or the high local strains of the host matrix. We address this challenge by employing a combination of radio-frequency (RF) field driving along the orientation and microwave (MW) dynamic pulse sequences.
