Quantum fluctuations spatial mode profiler
Charris Gabaldon, Pratik Barge, Savannah L. Cuozzo +4
The spatial mode is an essential component of an electromagnetic field description, yet it is challenging to characterize it for optical fields with low average photon number, such…
Optimizing the phase sensitivity of a Michelson interferometer with a two mode squeezed coherent input
Stav Haldar, Pratik J. Barge, Xiao-Qi Xiao +1
A Michelson-type interferometer with two-mode squeezed coherent state input is considered. Such an interferometer has a better phase sensitivity over the shot-noise limit by a fact…
Enhanced phase sensitivity in a Mach-Zehnder interferometer via photon recycling
Dong Li, Chun-Hua Yuan, Xiaoping Ma +4
We propose an alternative scheme for phase estimation in a Mach-Zehnder interferometer (MZI) with photon recycling. It is demonstrated that with the same coherent-state input and h…
Weak Thermal State Quadrature-Noise Shadow Imaging
Pratik J. Barge, Ziqi Niu, Savannah Cuozzo +4
In this work, we theoretically and experimentally demonstrate the possibility to create an image of an opaque object using a few-photon thermal optical field. We utilize the Quadra…
