Creation of quantum coherence with general measurement processes
Sanuja D. Mohanty, Gautam Sharma, Sk Sazim +2
Quantum measurement not only can destroy coherence but also can create it. Here, we estimate the maximum amount of coherence, one can create under a complete non-selective measurem…
Entangled Brachistochrone: Minimum Time to reach Target Entangled State
Arun Pati, Biswajit Pradhan, Pankaj Agrawal
We address the question: Given an arbitrary initial state and a general physical interaction what is the minimum time for reaching a target entangled state? We show that the minimu…
Quantum Work Relations under Trial Hamiltonians
Arun Kumar Pati, Mamata Sahoo, Biswajit Pradhan
The universal quantum work relation connects a functional of an arbitrary observable averaged over the forward process to the free energy difference and another functional averaged…
Generalized W-states and Quantum Communication Protocols
B. Pradhan, Pankaj Agrawal, A. K. Pati
We consider W-states and generalized W-states for -qubit systems. We obtain conditions to use these states as quantum resources to teleport unknown states. Only a limited class…
Task-Oriented Maximally Entangled States
Pankaj Agrawal, B. Pradhan
We introduce the notion of a task-oriented maximally entangled state (TMES). This notion depends on the tasks for which a quantum state is used as the resource. This concept may be…
Teleportation and Superdense coding with Genuine quadripartite entangled states
B. Pradhan, Pankaj Agrawal, A. K. Pati
We investigate the usefulness of different classes of genuine quadripartite entangled states as quantum resources for teleportation and superdense coding. We examine the possibilit…
