Quantum state transfer and periodicity in discrete-time quantum walks under non--Markovian dephasing noise
Monika Rani, Supriyo Dutta, Subhashish Banerjee
In quantum communication, quantum state transfer from one location to another in a quantum network plays a prominent role, where the impact of noise could be crucial. The idea of s…
Quantum teleportation of a qutrit state via a hypergraph state in a noisy environment
Souvik Giri, Supriyo Dutta
The concept of quantum teleportation is fundamental in the theory of quantum communication. Developing models of quantum teleportation in different physical scenario is a modern tr…
Non-Markovianity in Discrete-Time Open Quantum Random Walk on Arbitrary Graphs
Monika Rani, Supriyo Dutta, Subhashish Banerjee
In this work, we present a new model of the Discrete-Time Open Quantum Walk (DTOQW) applicable to an arbitrary graph, thereby going beyond the case of quantum walks on regular grap…
Discrete-Time Open Quantum Walks for Vertex Ranking in Graphs
Supriyo Dutta
This article presents a new quantum PageRank algorithm on graphs using discrete-time open quantum walks. Google's PageRank is a widely used algorithm for ranking the web pages on t…
Quantum routing in planar graph using perfect state transfer
Supriyo Dutta
In this article, we consider a spin-spin interaction network governed by Hamiltonian. The vertices and edges of the network represent the spin objects and their interacti…
Perfect state transfer using Markovian quantum walk
Supriyo Dutta
The quantum Perfect State Transfer (PST) is a fundamental tool of quantum communication in a network. It is not easy to achieve in practice. The original idea of PST depends on the…
Qudit States in Noisy Quantum Channels
Supriyo Dutta, Subhashish Banerjee, Monika Rani
In this work, we analyze a number of noisy quantum channels on a family of qudit states. The channels studied are the dit-flip noise, phase flip noise, dit-phase flip noise, depola…
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…
Phase Squeezing of Quantum Hypergraph States
Ramita Sarkar, Supriyo Dutta, Subhashish Banerjee +1
Corresponding to a hypergraph with vertices, a quantum hypergraph state is defined by , where…
Facets of quantum information under non-Markovian evolution
Javid Naikoo, Supriyo Dutta, Subhashish Banerjee
We consider two non-Markovian models: Random Telegraph Noise (RTN) and non-Markovian dephasing (NMD). The memory in these models is studied from the perspective of quantum Fisher i…
Sharma-Mittal Quantum Discord
Souma Mazumdar, Supriyo Dutta, Partha Guha
We demonstrate a generalization of quantum discord using a generalized definition of von-Neumann entropy, which is Sharma-Mittal entropy; and the new definition of discord is calle…
Condition for zero and non-zero discord in graph Laplacian quantum states
Supriyo Dutta, Bibhas Adhikari, Subhashish Banerjee
This work is at the interface of graph theory and quantum mechanics. Quantum correlations epitomize the usefulness of quantum mechanics. Quantum discord is an interesting facet of…
Quantum discord of states arising from graphs
Supriyo Dutta, Bibhas Adhikari, Subhashish Banerjee
Quantum discord refers to an important aspect of quantum correlations for bipartite quantum systems. In our earlier works we have shown that corresponding to every graph (combinato…
Bipartite separability and non-local quantum operations on graphs
Supriyo Dutta, Bibhas Adhikari, Subhashish Banerjee +1
In this paper we consider the separability problem for bipartite quantum states arising from graphs. Earlier it was proved that the degree criterion is the graph-theoretic counterp…
A graph theoretical approach to states and unitary operations
Supriyo Dutta, Bibhas Adhikari, Subhashish Banerjee
Building upon our previous work, on graphical representation of a quantum state by signless Laplacian matrix, we pose the following question. If a local unitary operation is applie…
