• Abstract summary: We investigate the use of a split-ring resonator incorporated with an atomic-vapor cell to improve sensitivity and the minimal detectable electric field of Rydberg atom-based sensors. By combining EIT with a heterodyne Rydberg atom-based mixer approach, the SRR allows for the a sensitivity of 5.5$mu$V/m$sqrtrm Hz$, which is two-orders of magnitude improvement in sensitivity than when the SRR is not used.

• Abstract: We investigate the use of a split-ring resonator (SRR) incorporated with an atomic-vapor cell to improve the sensitivity and the minimal detectable electric (E) field of Rydberg atom-based sensors. In this approach, a sub-wavelength SRR is placed around an atomic vapor-cell filled with cesium atoms for E-field measurements at 1.3~GHz. The SRR provides a factor of 100 in the enhancement of the E-field measurement sensitivity. Using electromagnetically induced transparency (EIT) with Aulter-Townes splitting, E-field measurements down to 5~mV/m are demonstrated with the SRR, while in the absence of the SRR, the minimal detectable field is 500~mV/m. We demonstrate that by combining EIT with a heterodyne Rydberg atom-based mixer approach, the SRR allows for the a sensitivity of 5.5~$\mu$V/m$\sqrt{{\rm Hz}}$, which is two-orders of magnitude improvement in sensitivity than when the SRR is not used.

  We model the 4-level and 5-level atomic system and compare how the transmission of the probe changes with different powers of the lasers used and strengths of the RF field. We find that the three-photon system boasts much narrower line widths compared to the conventional two-photon EIT. In addition to this, we calculate the expected sensitivity for the two-photon Rydberg sensor and find that the best achievable sensitivity is over an order of magnitude better than the current measured values of 5 uV/m/Hz.

  Superconducting micro-resonators in combination with quantum-limited Josephson parametric amplifiers lead to more than four orders of magnitude improvement in sensitivity of pulsed Electron Spin Resonance (ESR) measurements. We present a technique for coupling an ensemble of spins directly to a weakly nonlinear microwave resonator, which is engineered from a magnetic field-resilient thin superconducting film. We perform pulsed ESR measurements with a $1$pL effective mode volume and amplify the resulting spin signal using the same device, achieving a sensitivity of $2.8 times 103$ spins in a single-shot Hahn echo measurement at a temperature of 400
