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…
Realizing quantum nodes in space for cost-effective, global quantum communication: in-orbit results and next steps
Chithrabhanu Perumangatt, Tom Vergoossen, Alexander Lohrmann +6
Quantum sources and receivers operating on-board satellites are an essential building block for global quantumnetworks. SpooQy-1 is a satellite developed at the Centre for Quantum…
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…
Observing sub-Poissonian statistics of twisted single photons using oscilloscope
Nijil Lal, Biveen Shajilal, Ali Anwar +2
Heralded single photon sources (HSPS) from spontaneous parametric down-conversion are widely used as single photon sources. We study the photon number statistics of an HSPS carryin…
Engineering of orbital angular momentum spectrum of down-converted photons with mode-invariant pump
Anindya Banerji, Ali Anwar, Hrushikesh Sable +2
In this article we investigate the orbital angular momentum spectrum of photons produced in parametric down conversion process. We study how the transverse profile of the pump mode…
Controlling the biphoton orbital angular momentum eigenmodes using asymmetric pump vortex beam
M. V. Jabir, Ali Anwar, G. K. Samanta
We report on controlling the bi-photon orbital angular momentum (OAM) eigenmodes in the spontaneous parametric down conversion process by simply adjusting the asymmetry of the pump…
