Post-Markovian master equation à la microscopic collisional model
Tanmay Saha, Sahil, K. P. Athulya +1
We derive a completely positive post-Markovian master equation (PMME) from a microscopic Markovian collisional model framework, incorporating bath memory effects via a probabilisti…
Repeater-Based Quantum Communication Protocol: Maximizing Teleportation Fidelity with Minimal Entanglement
Arkaprabha Ghosal, Jatin Ghai, Tanmay Saha +2
Transmitting unknown quantum states to distant locations is crucial for distributed quantum information protocols. The seminal quantum teleportation scheme achieves this feat while…
Convex Optimization Approaches to Optimal Teleportation Fidelity in Linear Three-Party Networks
Arkaprabha Ghosal, Jatin Ghai, Tanmay Saha +2
We study the maximum achievable quantum teleportation fidelity between two distant parties, Alice and Charlie, where each of them share a bipartite quantum state only with a common…
Bond current in a mesoscopic ring -- signature of decoherence due to classical and quantum noise
Sushanta Dattagupta, Tanmay Saha
A three-site mesoscopic ring provides an ideal setting for an exact calculation of the bond current when the ring is threaded by an Aharonov-Bohm flux. The bond current is a measur…
Quantum homogenization in non-Markovian collisional model
Tanmay Saha, Arpan Das, Sibasish Ghosh
Collisional models are a category of microscopic framework designed to study open quantum systems. The framework involves a system sequentially interacting with a bath comprised of…
