Distributed Quantum Dense Coding Enhanced With Non-classical Routing
Pratham Hullamballi, Aparajita Bhattacharyya, Ujjwal Sen
We propose a distributed quantum dense coding protocol that uses a control system to superpose two dense coding processes, allowing us to simultaneously and coherently encode and n…
Erasure cost of a quantum process: A thermodynamic meaning of the dynamical min-entropy
Himanshu Badhani, Dhanuja GS, Swati Choudhary +2
The erasure of information is fundamentally an irreversible logical operation, carrying profound consequences for the energetics of computation and information processing. We inves…
Path superposition activating perfect quantum teleportation ability for separable states
Sayan Mondal, Priya Ghosh, Ujjwal Sen
Quantum teleportation is a quintessential quantum communication protocol that enables the transmission of an arbitrary quantum state between two distant parties without physically…
Disappearance of measurement-induced phase transition in a quantum spin system for large sizes
Paranjoy Chaki, Protyush Nandi, Ujjwal Sen +1
Measurement-induced phase transitions are often studied in random quantum circuits, with local measurements performed with a certain probability. We present here a model where a gl…
Role of energy-invariant assistants in energy extraction from quantum batteries
Paranjoy Chaki, Aparajita Bhattacharyya, Kornikar Sen +1
We investigate the role of energy-invariant assistants in energy extraction from quantum batteries. To this end, for energy extraction, we restrict ourselves to unitaries that join…
Entanglement concentration via measurement:- role of imaginarity
Indranil Biswas, Subrata Bera, Ujjwal Sen +2
The role of complex numbers in quantum theory extends beyond mathematical convenience, having recently been formalized as a resource under the framework of the resource theory of i…
