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…
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…
Quantum key distribution with multiphoton pulses: An advantage
Ayan Biswas, Anindya Banerji, Nijil Lal +3
In this article, we introduce a quantum key distribution protocol for the line of sight channels based on coincidence measurements. We present a proof-of-concept implementation of…
Single photon sources with different spatial modes
Nijil Lal, Anindya Banerji, Ayan Biswas +2
We study the correlation properties of single photons carrying orbital angular momentum (OAM) in a Hanbury Brown and Twiss (HBT) type experiment. We have characterized single photo…
