On the trace-zero doubly stochastic matrices of order 5
Amrita Mandal, Bibhas Adhikari
We propose a graph theoretic approach to determine trace of product of two permutation matrices through a weighted digraph representation of the permutation matrices. Consequently,…
Structural balance and spectral properties of generalized corona product of signed graphs
Amrik Singh, Ravi Srivastava, Bibhas Adhikari +1
In this paper, we extend our earlier proposal of corona product of signed graphs into generalized corona product of signed graphs inspired by the generalized corona product of unsi…
Discrete-time quantum walks on Cayley graphs of Dihedral groups using generalized Grover coins
Rohit Sarma Sarkar, Bibhas Adhikari
In this paper we study discrete-time quantum walks on Cayley graphs corresponding to Dihedral groups, which are graphs with both directed and undirected edges. We consider the walk…
Modeling interdisciplinary interactions among Physics, Mathematics & Computer Science
Rima Hazra, Mayank Singh, Pawan Goyal +2
Interdisciplinarity has over the recent years have gained tremendous importance and has become one of the key ways of doing cutting edge research. In this paper we attempt to model…
Scalable quantum circuits for -qubit unitary matrices
Rohit Sarma Sarkar, Bibhas Adhikari
This work presents an optimization-based scalable quantum neural network framework for approximating -qubit unitaries through generic parametric representation of unitaries, whi…
A characterization of orthogonal permutative matrices of order 4
Amrita Mandal, Bibhas Adhikari
Orthogonal matrices which are linear combinations of permutation matrices have attracted enormous attention in quantum information and computation. In this paper, we provide a comp…
