Qutrit-based Synthetic Three-Level System
Surajit Sen, Tushar Kanti Dey
We present a theoretical framework based on the group to construct synthetic three-level configurations from a two-qutrit system consisting of two three-level subsystems. U…
Quantum Teleportation of a Single Qutrit using Two-Qutrit Entangled States
Surajit Sen, Tushar Kanti Dey, Anushree Bhattacharjee +1
We demonstrate quantum teleportation of a qutrit system using a complete set of two-qutrit entangled states obtained from the representation theory of the SU(3) group. All measurem…
Unitary and non-unitary operators leverage perfect and imperfect single qutrit teleportation
Sovik Roy, Anushree Pandey, Tushar Kanti Dey +1
Teleportation, a novel scheme, initially posited by Bennett \textit{et.al}, has been studied here in the context of sending a single qutrit from Alice to Bob using two qutrit entan…
Bloch Sphere of the Qutrit System
Surajit Sen, Tushar Kanti Dey
We present a novel method to study the Bloch space of the qutrit system by examining the Bloch trajectories in it. Since such system is inherently a three-level quantum system, the…
An Inequality for Entangled Qutrits in SU(3) basis
Surajit Sen, Tushar Kanti Dey
It is well-known from the representation theory of particle physics that the tensor product of two fundamental representation of SU(2) and SU(3) group can be decomposed to obtain t…
Resonance fluorescence in , and -- type three-level configurations
Surajit Sen, Tushar Kanti Dey, Bimalendu Deb
We theoretically study the resonance fluorescence spectra of the lambda (), vee () and cascade () type three-level configurations. It is shown that each system with two de…
Entangled States of Qutrit Bipartite System
Surajit Sen, Tushar Kanti Dey
We develop a systematic method to construct the Bell states of a qubit bipartite system while taking group as the basis group. An alternative formulation of fidelity, calle…
Collapse and Revival Oscillation in Double Jaynes-Cummings Model
Surajit Sen, Tushar Kanti Dey, Mihir Ranjan Nath
We develop a systematic method of solving two non-interacting Jaynes-Cummings models by using the dressed state formalism in Hilbert space . It is s…
A unified approach to -, - and -type systems with one continuum
Surajit Sen, Tushar Kanti Dey, Bimalendu Deb
We present a systematic approach to classify the three-level-like models with two bound states coupled to a continuum. It is shown that, when one of the discrete levels of usual th…
Comparison of Electromagnetically Induced Transparency in lambda, cascade and vee three-level systems
Surajit Sen, Tushar Kanti Dey, Mihir Ranjan Nath +1
We discuss the Electromagnetically Induced Transparency (EIT) in lambda, cascade and vee type three-level systems where the Hamiltonian and the Lindblad term of each configuration…
Bloch space structure, the qutrit wave function and atom-field entanglement in three-level systems
Surajit Sen, Mihir Ranjan Nath, Tushar Kanti Dey +1
We have given a novel formulation of the exact solutions for the lambda, vee and cascade three-level systems where the Hamiltonian of each configuration is expressed in the SU(3) b…

Surajit Sen, Mihir Ranjan Nath, Tushar Kanti Dey +1
The cascade, lambda and vee type of three-level systems are shown to be described by three different Hamiltonians in the SU(3) basis. We investigate the Bloch space structure of ea…

Mihir Ranjan Nath, Tushar Kanti Dey, Surajit Sen +1
We have exactly solved a model of equidistant cascade four-level system interacting with a single-mode radiation field both semiclassically and quantum mechanically by exploiting i…
