Generation of large Fock states from coherent states using Kerr interaction and displacement
Nilakantha Meher, Anirban Pathak, S. Sivakumar
We discuss a scheme to generate large Fock states. The scheme involves repeatedly applying an experimentally feasible unitary transformation to convert a semiclassical state into a…
Frequency drift corrected ultra-stable laser through phase-coherent fiber producing a quantum channel
Stanley Johnson, Sandeep Mishra, Anirban Pathak +1
Phase coherent fibers (PCF) are essential to distribute nearly monochromatic photons, ultra-stable in their frequency and phases, which have demanding requirements for state-of-the…
State-Dependent Quantum Copying: an adaptive ancillary systems and its limitations
Guruprasad Kadam
In this work, we introduce a novel state-dependent quantum cloning (copying) process by introducing a new class of ancillary system -- an adaptive ancilla -- modifying the conventi…
Finite and Asymptotic Key Analysis for CubeSat-Based BB84 QKD with Elliptical Beam Approximation
Muskan, Arindam Dutta, Subhashish Banerjee
Satellite and CubeSat-based quantum key distribution (QKD) presents a promising solution for secure long-distance communication by transmitting quantum keys through free space, wit…
Satellite-based communication for phase-matching measurement-device-independent quantum key distribution
Arindam Dutta, Subhashish Banerjee, Anirban Pathak
This study investigates the feasibility of the phase-matching measurement-device-independent quantum key distribution (PM-MDI QKD) protocol proposed by Lin and Lütkenhaus for satel…
Creating two-qudit maximally entangled quantum link through bulk
Keshav Das Agarwal, Sudip Kumar Haldar, Aditi Sen De
We design a setup for creating almost maximally entangled two-qudit link between distant nodes which are weakly coupled with the interacting spin-s bulk (processor). We exhibit tha…
