Using random coherent states to mimic quantum illumination

Thomas Brougham, Nigam Samantaray, John Jeffers

Quantum illumination uses quantum correlations to enhance the detection of an object in the presence of background noise. This advantage has been shown to exist even if one uses no…

Quantum illumination with multiplexed photodetection

Hao Yang, Nigam Samantaray, John Jeffers

The advantages of using quantum states of light for object detection are often highlighted in schemes that use simultaneous and optimal measurements. Here, we describe a theoretica…

Un-symmetric photon subtraction: a method for generating high photon number states and their relevance to loss estimation at ultimate quantum limit

N. Samantaray, J. C. F. Matthews, J. G. Rarity

We have studied theoretical un-symmetric multi-photon subtracted twin beam state and demonstrated a method for generating states that resembles to high photon number states with th…

Poissonian twin beam states and the effect of symmetrical photon subtraction in loss estimations

N. Samantaray, J. C. F. Matthews, J. G. Rarity

We have devised an experimentally realizable model generating twin beam states whose individual beam photon statistics are varied from thermal to Poissonian keeping the non-classic…

A practical model of twin-beam experiments for sub-shot-noise absorption measurements

Jason D. Mueller, Nigam Samantaray, Jonathan C. F. Matthews

Quantum-intensity-correlated twin beams of light can be used to measure absorption with precision beyond the classical shot-noise limit. The degree to which this can be achieved wi…

Single phase and correlated phase estimation with multi-photon annihilated squeezed vacuum states: An energy balancing scenario

Nigam Samantaray, Ivano Ruo Berchera, Ivo. P. Degiovanni

In the last years, several works have demonstrated the advantage of photon subtracted Gaussian states for various quantum optics and information protocols. In most of these works,…
