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…
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…
Selective tuning of Hilbert spaces in states encoded with spatial modes of light
Ali Anwar, Nijil Lal, Shashi Prabhakar +1
Spatial modes of light directly give the most easily accessible degree of freedom that span an infinite dimensional Hilbert space. The higher dimensional spatial mode entanglement…
Near-perfect measuring of full-field transverse-spatial modes of light
Markus Hiekkamäki, Shashi Prabhakar, Robert Fickler
Along with the growing interest in using the transverse-spatial modes of light in quantum and classical optics applications, developing an accurate and efficient measurement method…
