Generation of pulsed bipartite entanglement using four-wave mixing
Quentin Glorieux, Jeremy B. Clark, Neil V. Corzo +1
Using four-wave mixing in a hot atomic vapor, we generate a pair of entangled twin beams in the microsecond pulsed regime near the D1 line of Rb, making it compatible with c…
Experimental characterization of Gaussian quantum discord generated by four-wave mixing
Ulrich Vogl, Ryan T. Glasser, Quentin Glorieux +3
We experimentally determine the quantum discord present in two-mode squeezed vacuum generated by a four-wave mixing process in hot rubidium vapor. The frequency spectra of the disc…
Advanced Detection of Information in Optical Pulses with Negative Group Velocity
Ulrich Vogl, Ryan T. Glasser, Paul D. Lett
In this letter we experimentally demonstrate that the signal velocity, defined as the earliest time when a signal is detected above the realistic noise floor, may be altered by a r…
A Compact Source for Quantum Image Processing with Four-wave Mixing in Rubidium-85
Ulrich Vogl, Ryan T. Glasser, Paul D. Lett
We have built a compact light source for bright squeezed twin-beams at 795\,nm based on four-wave-mixing in atomic Rb vapor. With a total optical power of 400\,mW derived fr…
Imaging using quantum noise properties of light
Jeremy B. Clark, Zhifan Zhou, Quentin Glorieux +2
We show that it is possible to estimate the shape of an object by measuring only the fluctuations of a probing field, allowing us to expose the object to a minimal light intensity.…
Demonstration of images with negative group velocities
Ryan T. Glasser, Ulrich Vogl, Paul D. Lett
We report the experimental demonstration of the superluminal propagation of multi-spatial-mode images via four-wave mixing in hot atomic vapor, in which all spatial sub-regions pro…
