Effect of imperfect homodyne visibility on multi-spatial-mode two-mode squeezing measurements
Prasoon Gupta, Rory W. Speirs, Kevin M. Jones +1
We study the effect of homodyne detector visibility on the measurement of quadrature squeezing for a spatially multi-mode source of two-mode squeezed light. Sources like optical pa…
Twin-beam intensity-difference squeezing below 10 Hz
Meng-Chang Wu, Bonnie L. Schmittberger, Nicholas R. Brewer +3
We report the generation of strong, bright-beam intensity-difference squeezing down to measurement frequencies below 10 Hz. We generate two-mode squeezing in a four-wave mixing (4W…
Optimized phase sensing in a truncated SU(1,1) interferometer
Prasoon Gupta, Bonnie L. Schmittberger, Brian E. Anderson +2
Homodyne detection is often used for interferometers based on nonlinear optical gain media. For the configuration of a seeded, 'truncated SU(1,1)' interferometer Anderson et al. (P…
Improved measurement of two-mode quantum correlations using a phase-sensitive amplifier
Tian Li, Brian E. Anderson, Travis Horrom +3
We demonstrate the ability of a phase-sensitive amplifier (PSA) to pre-amplify a selected quadrature of one mode of a two-mode squeezed state in order to improve the measurement of…
The effect of input phase modulation to a phase-sensitive optical amplifier
Tian Li, Brian E. Anderson, Travis Horrom +2
Many optical applications depend on amplitude modulating optical beams using devices such as acousto-optical modulators (AOMs) or optical choppers. Methods to add amplitude modulat…
Quantum mutual information of an entangled state propagating through a fast-light medium
Jeremy B. Clark, Ryan T. Glasser, Quentin Glorieux +4
Although it is widely accepted that classical information cannot travel faster than the speed of light in vacuum, the behavior of quantum correlations and quantum information propa…
