Perfect state transfer on hypercubes and its implementation using superconducting qubits
Siddhant Singh, Bibhas Adhikari, Supriyo Dutta +1
We propose a protocol for perfect state transfer between any pair of vertices in a hypercube. Given a pair of distinct vertices in the hypercube we determine a sub-hypercube that c…
Preserving spectral properties of structured matrices under structured perturbations
Tinku Ganai, Bibhas Adhikari
This paper is devoted to the study of preservation of eigenvalues, Jordan structure and complementary invariant subspaces of structured matrices under structured perturbations. Per…
A model for the spread of an epidemic from local to global: A case study of COVID-19 in India
Buddhananda Banerjee, Pradumn Kumar Pandey, Bibhas Adhikari
In this paper we propose an epidemiological model for the spread of COVID-19. The dynamics of the spread is based on four fundamental categories of people in a population: Tested a…
Why lockdown : On the spread of SARS-CoV-2 in India, a network approach
Pradumn Kumar Pandey, Bibhas Adhikari
We analyze the time series data of number of districts or cities in India that are affected by COVID-19 from March 01, 2020 to April 17, 2020. We study the data in the framework of…
Periodicity of lively quantum walks on cycles with generalized Grover coin
Rohit Sarma Sarkar, Amrita Mandal, Bibhas Adhikari
In this paper we extend the study of three state lively quantum walks on cycles by considering the coin operator as a linear sum of permutation matrices, which is a generalization…
Updating structured matrix pencils with no spillover effect on unmeasured spectral data and deflating pair
Bibhas Adhikari, Biswa Nath Datta, Tinku Ganai +1
This paper is devoted to the study of perturbations of a matrix pencil, structured or unstructured, such that a perturbed pencil will reproduce a given deflating pair while maintai…
