Polarization selective Dove prism
P. A. Ameen Yasir, Sandeep K. Goyal
We propose a passive all optical device capable of transforming the orbital angular momentum (OAM) state of light conditioned over the polarization states. The efficiency of this d…
Persistence of Topological Phases in Non-Hermitian Quantum Walks
Vikash Mittal, Aswathy Raj, Sanjib Dey +1
Discrete-time quantum walks are known to exhibit exotic topological states and phases. Physical realization of quantum walks in a noisy environment may destroy these phases. We inv…
Quantum -nearest neighbors algorithm
Afrad Basheer, A. Afham, Sandeep K. Goyal
One of the simplest and most effective classical machine learning algorithms is the -nearest neighbors algorithm (NN) which classifies an unknown test state by finding the $k…
Role of Bell-CHSH violation and local filtering in quantum key distribution
Jaskaran Singh, Sibasish Ghosh, Arvind +1
In this article, we analyse the relationship between the Bell violation and the secure key rate of entanglement assisted quantum key distribution (QKD) protocols. Specifically, we…
Robustness of intra-atomic frequency comb based quantum memory against fluctuating environment
G. P. Teja, Sandeep K. Goyal
In this article, we study the robustness of the intra-atomic frequency comb (I-AFC) based quantum memory against various environmental factors. The effect of the environment is inc…
