Spatiotemporal Multiplexed Rydberg Receiver
Samuel H. Knarr, Victor G. Bucklew, Jerrod Langston +4
Rydberg states of alkali atoms, where the outer valence electron is excited to high principal quantum numbers, have large electric dipole moments allowing them to be used as sensit…
Introduction to the Absolute Brightness and Number Statistics in Spontaneous Parametric Down-Conversion
James Schneeloch, Samuel H. Knarr, Daniela F. Bogorin +6
As a tutorial, we examine the absolute brightness and number statistics of photon pairs generated in Spontaneous Parametric Down-Conversion (SPDC) from first principles. In doing s…
Frequency-modulated continuous-wave LiDAR compressive depth-mapping
Daniel J. Lum, Samuel H. Knarr, John C. Howell
We present an inexpensive architecture for converting a frequency-modulated continuous-wave LiDAR system into a compressive-sensing based depth-mapping camera. Instead of raster sc…
Compressive Direct Imaging of a Billion-Dimensional Optical Phase-Space
Samuel H. Knarr, Daniel J. Lum, James Schneeloch +1
Optical phase-spaces represent fields of any spatial coherence, and are typically measured through phase-retrieval methods involving a computational inversion, interference, or a r…
Compressively characterizing high-dimensional entangled states with complementary, random filtering
Gregory A. Howland, Samuel H. Knarr, James Schneeloch +2
The resources needed to conventionally characterize a quantum system are overwhelmingly large for high- dimensional systems. This obstacle may be overcome by abandoning traditional…
Position-Momentum Bell-Nonlocality with Entangled Photon Pairs
James Schneeloch, Samuel H. Knarr, Daniel J. Lum +1
Witnessing continuous-variable Bell nonlocality is a challenging endeavor, but Bell himself showed how one might demonstrate this nonlocality. Though Bell nearly showed a violation…
Fast Hadamard transforms for compressive sensing of joint systems: measurement of a 3.2 million-dimensional bi-photon probability distribution
Daniel J. Lum, Samuel H. Knarr, John C. Howell
We demonstrate how to efficiently implement extremely high-dimensional compressive imaging of a bi-photon probability distribution. Our method uses fast-Hadamard-transform Kronecke…
Demonstrating Continuous Variable EPR Steering in spite of Finite Experimental Capabilities using Fano Steering Bounds
James Schneeloch, Samuel H. Knarr, Gregory A. Howland +1
We show how one can demonstrate continuous-variable Einstein-Podolsky-Rosen (EPR) steering without needing to characterize entire measurement probability distributions. To do this,…
