Non-monotonic dependence of OAM Schmidt spectrum on crystal thickness
Harshal Jain, Suman Karan, Radhika Prasad +1
The orbital angular momentum (OAM) of photons provides a high-dimensional resource for quantum information protocols. The dimensionality of OAM-entangled states generated via spont…
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…
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…
Structured position-momentum entangled two-photon fields
Radhika Prasad, Sanjana Wanare, Suman Karan +3
Structured optical fields have led to several ground-breaking techniques in classical imaging and microscopy. At the same time, in the quantum domain, position-momentum entangled p…
