Fundamental Sensitivity Bounds for Quantum Enhanced Optical Resonance Sensors Based on Transmission and Phase Estimation
Mohammadjavad Dowran, Timothy S. Woodworth, Ashok Kumar +1
Quantum states of light can enable sensing configurations with sensitivities beyond the shot-noise limit (SNL). In order to better take advantage of available quantum resources and…
Einstein-Podolsky-Rosen Paradox with Position-Momentum Entangled Macroscopic Twin Beams
Ashok Kumar, Gaurav Nirala, Alberto M. Marino
Spatial entanglement is at the heart of quantum enhanced imaging applications and high-dimensional quantum information protocols. In particular, for imaging and sensing application…
Spatial squeezing in bright twin beams generated with four-wave mixing: constraints on characterization with an EMCCD camera
Ashok Kumar, Alberto M. Marino
The observation of spatial quantum noise reduction, or spatial squeezing, with a large number of photons can lead to a significant advantage in quantum imaging and quantum metrolog…
Quantum-Enhanced Plasmonic Sensing
Mohammadjavad Dowran, Ashok Kumar, Benjamin J. Lawrie +2
Quantum resources can enhance the sensitivity of a device beyond the classical shot noise limit and, as a result, revolutionize the field of metrology through the development of qu…
Spatial distribution of Spontaneous Parametric Down-Converted Photons for higher order Optical Vortices
Shashi Prabhakar, Salla Gangi Reddy, A Aadhi +4
We make a source of entangled photons (SEP) using spontaneous parametric down-conversion (SPDC) in a non-linear crystal and study the spatial distribution of photon pairs obtained…
