Imaging inspired characterization of single photons carrying orbital angular momentum
Vimlesh Kumar, Varun Sharma, Sandeep Singh +4
We report on an imaging-inspired measurement of orbital angular momentum (OAM) using only a simple tilted lens and an Intensified Charged Coupled Device (ICCD) camera, allowing us…
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…
Experimental Side Channel Analysis of BB84 QKD Source
Ayan Biswas, Anindya Banerji, Pooja Chandravashi +2
A typical implementation of BB84 protocol for quantum communication uses four laser diodes for transmitting weak coherent pulses, which may not have the same characteristics. We ha…
Polarization-orbital angular momentum duality assisted entanglement observation for indistinguishable photons
Nijil Lal, Sarika Mishra, Anju Rani +3
Duality in the entanglement of identical particles manifests that entanglement in only one variable can be revealed at a time. We demonstrate this using polarization and orbital an…
Maximum Violation of Monogamy of Entanglement for Indistinguishable Particles by Measures that are Monogamous for Distinguishable Particles
Goutam Paul, Soumya Das, Anindya Banerji
Two important results of quantum physics are the \textit{no-cloning} theorem and the \textit{monogamy of entanglement}. The former forbids the creation of an independent and identi…
Hyper-hybrid entanglement, indistinguishability, and two-particle entanglement swapping
Soumya Das, Goutam Paul, Anindya Banerji
Hyper-hybrid entanglement for two indistinguishable bosons has been recently proposed by Li \textit{et al.} [Y. Li, M. Gessner, W. Li, and A. Smerzi, \href{https://doi.org/10.1103/…
