Quantum interferometry using coherent beam stimulated parametric down-conversion
Aziz Kolkiran, G. S. Agarwal
We show how stimulated parametric processes can be employed in experiments on beyond the diffraction limit to overcome the problem of low visibility obtained by using spontaneous d…

Heisenberg limited Sagnac interferometry
Aziz Kolkiran, G S Agarwal
We show how the entangled photons produced in parametric down conversion can be used to improve the sensitivity of a Sagnac interferometer. Two-photon and four-photon coincidences…

Towards Heisenberg Limit in Magnetometry with Parametric Down Converted Photons
Aziz Kolkiran, G. S. Agarwal
Recent theoretical and experimental papers have shown how one can achieve Heisenberg limited measurements by using entangled photons. Here we show how the photons in non-collinear…
