Radial Schmidt mode detector of entangled photons
Radhika Prasad, Nilakshi Senapati, Abhinandan Bhattacharjee +1
High-dimensional spatially entangled two-photon state generated by spontaneous parametric down-conversion process (SPDC) has become a promising resource for several quantum informa…
Measuring the complete set of spatial Schmidt modes of entangled two-photon fields
Radhika Prasad, Nilakshi Senapati, Abhinandan Bhattacharjee +2
Spontaneous parametric down-conversion (SPDC) is the most widely-used source of high-dimensional entangled two-photon states, and the entanglement in the spatial degree of freedom…
Theory of temporal three-photon interference
Nilakshi Senapati, Girish Kulkarni, Anand K. Jha
The recent demonstrations of cascaded PDC (CPDC) and the hopeful prospects of realizing third-order PDC (TOPDC) for the generation of three-photon entangled states are paving the w…
Super-resolution imaging of azimuthal features with illumination carrying OAM
Nilakshi Senapati, Abhinandan Bhattacharjee, Kedar Khare +1
Super-resolution imaging refers to imaging techniques that surpass the Rayleigh resolution limit. One standard way to achieve super-resolution is by structuring the phase of the fi…
An experimental technique for measuring radial coherence
Radhika Prasad, Nilakshi Senapati, Suman Karan +4
Coherence refers to correlations between field vibrations at two separate points in degrees of freedom such as space, time, and polarisation. In the context of space, coherence the…
