Multi-channel entanglement distribution using spatial multiplexing from four-wave mixing in atomic vapor
Prasoon Gupta, Travis Horrom, Brian E. Anderson +2
Four-wave mixing in atomic vapor allows for the generation of multi-spatial-mode states of light containing many pairs of two-mode entangled vacuum beams. This in principle can be…
All-atomic generation and noise-quadrature filtering of squeezed vacuum in hot Rb vapor
Travis Horrom, Gleb Romanov, Irina Novikova +1
With our all-atomic squeezing and filtering setup, we demonstrate control over the noise amplitudes and manipulation of the frequency-dependent squeezing angle of a squeezed vacuum…
Quantum Enhanced Magnetometer with Low-Frequency Squeezing
Travis Horrom, Robinjeet Singh, Jonathan P. Dowling +1
We report the demonstration of a magnetometer with noise-floor reduction below the shot-noise level. This magnetometer, based on a nonlinear magneto-optical rotation effect, is enh…
All-atomic source of squeezed vacuum with full pulse-shape control
Travis Horrom, Irina Novikova, Eugeniy E. Mikhailov
We report on the generation of pulses of a low-frequency squeezed vacuum with noise suppression >2 dB below the standard quantum limit in a hot resonant 87 Rb vapor with polarizati…
Quadrature noise in light propagating through a cold 87Rb atomic gas
Travis Horrom, Arturo Lezama, Salim Balik +2
We report on the study of the noise properties of laser light propagating through a cold 87Rb atomic sample held in a magneto-optical trap. The laser is tuned around the Fg = 2 \ri…
