Basis-Independent Coherence Dynamics of Tripartite States under Pure Dephasing
Sovik Roy, Abhijit Mandal
Quantum coherence is a fundamental quantum resource whose preservation under environmental interactions is essential for quantum information processing. While most studies have foc…
Coherence thermometry using multipartite quantum systems
Pranav Perumalsamy, Abhijit Mandal, Sovik Roy +1
Accurate temperature measurement at the quantum scale is becoming increasingly important for emerging quantum technologies, motivating the development of quantum thermometry based…
Near perfect noisy quantum teleportation by one-sided environment engineering
Md Manirul Ali, Sovik Roy, Dipankar Home
Achieving near-unity fidelity of Quantum Teleportation (QT) in a noisy environment is an essential requirement for its real-world applications. Towards this goal, we devise a disti…
Resilience of Quantum Teleportation Fidelity for Bipartite Mixed States near Schwarzschild and Dilaton Black Holes
Abhijit Mandal, Sovik Roy
We investigate the robustness of quantum teleportation in the presence of strong gravitational fields by analysing bipartite mixed states derived from tripartite GHZ and W-class st…
Environment engineering to protect quantum coherence in tripartite systems under dephasing noise
Sovik Roy, Aahaman Kalaiselvan, Chandrashekar Radhakrishnan +1
The practical success of quantum technology hinges on sustaining quantum coherence, which is vulnerable to environmental interactions causing decoherence. We investigate coherence…
Dephasing-Induced Distribution of Entanglement in Tripartite Quantum Systems
Sovik Roy, Md. Manirul Ali, Abhijit Mandal +1
Preserving multipartite entanglement amidst decoherence poses a pivotal challenge in quantum information processing. However, assessing multipartite entanglement in mixed states am…
Teleportation of unknown qubit via Star type tripartite states
Anushree Pandey, Abhijit Mandal, Sovik Roy
Eylee Jung \textit{et.al}\cite{jung2008} had conjectured that is a necessary and sufficient condition for the perfect two-party teleportation and consequently…
Certified Quantumness via Single-Shot Temporal Measurements
Md Manirul Ali, Sovik Roy
Bell-Kochen-Specker theorem states that a non-contextual hidden-variable theory cannot completely reproduce the predictions of quantum mechanics. Asher Peres gave a remarkably simp…
