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…
Observation of OAM non-conservation in entangled photon generation
Suman Karan, Anand K. Jha
Orbital angular momentum (OAM)-entangled states produced by spontaneous parametric down-conversion (SPDC) are considered ideal for realizing high-dimensional entangled states, whic…
Broadband uniform-efficiency OAM-mode detector
Suman Karan, Martin P. Van Exter, Anand K. Jha
The high-dimensional basis of orbital angular momentum (OAM) has several added and unique advantages for photonics quantum technologies compared to the polarization basis, which is…
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…
