Basis-Independent Coherence Dynamics of Tripartite States under Pure Dephasing
Sovik Roy, Abhijit Mandal
The paper studies how basis‑independent quantum coherence in three‑partite states evolves under various dephasing environments, showing that collective and non‑Markovian noise can…
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…
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…
Near-perfect Noisy Quantum State Teleportation
Md Manirul Ali, Sovik Roy, Dipankar Home
Achieving high fidelity of quantum teleportation (QT) in a noisy environment is an essential requirement for its real-world applications. To this end, we devise a distinctive proto…
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…
