Rydberg state engineering: A comparison of tuning schemes for continuous frequency sensing
Samuel Berweger, Nikunjkumar Prajapati, Alexandra B. Artusio-Glimpse +11
On-resonance Rydberg atom-based radio-frequency (RF) electric field sensing methods remain limited by the narrow frequency signal detection bands available by resonant transitions.…
Rydberg atom-based field sensing enhancement using a split-ring resonator
Christopher L. Holloway, Nikunjkumar Prajapati, Alexandra B. Artusio-Glimpse +4
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 at…
Determining the Angle-of-Arrival of an Radio-Frequency Source with a Rydberg Atom-Based Sensor
Amy K. Robinson, Nikunjkumar Prajapati, Damir Senic +3
In this work, we demonstrate the use of a Rydberg atom-based sensor for determining the angle-of-arrival of an incident radio-frequency (RF) wave or signal. The technique uses elec…
Quantum-Enhanced Two-Photon Spectroscopy Using Two-mode Squeezed Light
Nikunjkumar Prajapati, Ziqi Niu, Irina Novikova
We investigate the prospects of using two-mode intensity squeezed twin-beams, generated in Rb vapor, to improve the sensitivity of spectroscopic measurements by engaging two-photon…
Quantum-Limited Squeezed Light Detection with a Camera
Elisha S. Matekole, Savannah L. Cuozzo, Nikunjkumar Prajapati +6
We present a technique for squeezed light detection based on direct imaging of the displaced-squeezed-vacuum state using a CCD camera. We show that the squeezing parameter can be a…
Polarization-Based Truncated SU(1,1) Interferometer based on Four-wave Mixing in Rb vapor
Nikunjkumar Prajapati, Irina Novikova
We propose and demonstrate a polarization-based truncated SU(1,1) interferometer that outputs the desired optical joint-quadrature of a two-mode squeezed vacuum field and allows it…
