Anisotropic Spatial Entanglement
Satyajeet Patil, Shashi Prabhakar, Ayan Biswas +2
The photon-pairs generated through spontaneous parametric down-conversion (SPDC) possess strong correlations in their transverse position and momentum degrees of freedom. For such…
Intensity correlations in perturbed optical vortices: Diagnosis of the topological charge
Patnala Vanitha, Bhargavi Manupati, Salla Gangi Reddy +3
We propose and experimentally verify a novel scheme for diagnosing the order of a perturbed optical vortex using its 2-D spatial autocorrelation function. The order of a vortex was…
BBM92 quantum key distribution over a free space dusty channel of 200 meters
Sarika Mishra, Ayan Biswas, Satyajeet Patil +7
Free space quantum communication assumes importance as it is a precursor for satellite-based quantum communication needed for secure key distribution over longer distances. Prepare…
Size invariant twisted optical modes for efficient generation of higher dimensional quantum states
Ali Anwar, Shashi Prabhakar, R. P. Singh
Optical vortex beams are profiled as helical wavefronts with a phase singularity carrying an orbital angular momentum (OAM) associated with their spatial distribution. The transver…
Endless Fun in high dimensions -- A Quantum Card Game
Lea Kopf, Markus Hiekkamäki, Shashi Prabhakar +1
Quantum technologies, i.e., technologies benefiting from the features of quantum physics such as objective randomness, superposition, and entanglement, have enabled an entirely dif…
High-accuracy longitudinal position measurement using self-accelerating light
Shashi Prabhakar, Stephen Plachta, Marco Ornigotti +1
Radially self-accelerating light exhibits an intensity pattern that describes a spiraling trajectory around the optical axis as the beam propagates. In this article, we show in sim…
