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…
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…
Optimal phase measurements with bright and vacuum-seeded SU(1,1) interferometers
B. E. Anderson, B. L. Schmittberger, P. Gupta +2
The SU(1,1) interferometer can be thought of as a Mach-Zehnder interferometer with its linear beamsplitters replaced with parametric nonlinear optical processes. We consider the ca…
Phase sensing beyond the standard quantum limit with a truncated SU(1,1) interferometer
Brian E. Anderson, Prasoon Gupta, Bonnie L. Schmittberger +4
An SU(1,1) interferometer replaces the beamsplitters in a Mach-Zehnder interferometer with nonlinear interactions and offers the potential of achieving high phase sensitivity in ap…
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…
