Quantum work beyond classical (commuting) limits

Sumit Rout, Aravinth Balaji Ravichandran, Paweł Horodecki +1

Free energy fixes the maximum work of a thermodynamic process once the state and Hamiltonian are specified. A work-extraction task asks a different question: how much average work…

Facets of Non-locality and Advantage in Entanglement-Assisted Classical Communication Tasks

Sumit Rout, Anubhav Chaturvedi, Some Sankar Bhattacharya +1

We reveal key connections between non-locality and advantage in correlation-assisted classical communication. First, using the wire-cutting technique, we provide a Bell inequality…

Randomness-free Detection of Non-projective Measurements: Qubits & beyond

Sumit Rout, Some Sankar Bhattacharya, Paweł Horodecki

Non-projective measurements play a crucial role in various information-processing protocols. In this work, we propose an operational task to identify measurements that are neither…

Unbounded Quantum Advantage in Communication with Minimal Input Scaling

Sumit Rout, Nitica Sakharwade, Some Sankar Bhattacharya +2

In communication complexity-like problems, previous studies have shown either an exponential quantum advantage or an unbounded quantum advantage with an exponentially large input s…

Quantum Advantage for Shared Randomness Generation

Tamal Guha, Mir Alimuddin, Sumit Rout +3

Sharing correlated random variables is a resource for a number of information theoretic tasks such as privacy amplification, simultaneous message passing, secret sharing and many m…

Multiparty orthogonal product states with minimal genuine nonlocality

Sumit Rout, Ananda G. Maity, Amit Mukherjee +2

Nonlocality without entanglement and its subsequent generalizations offer deep information-theoretic insights and subsequently find several useful applications. Concept of genuinel…

Genuinely Nonlocal Product Bases: Classification and Entanglement Assisted Discrimination

Sumit Rout, Ananda G. Maity, Amit Mukherjee +2

An orthogonal product basis of a composite Hilbert space is genuinely nonlocal if the basis states are locally indistinguishable across every bipartition. From an operational point…

Quantum Locker Using a Novel Verification Algorithm and Its Experimental Realization in IBM Quantum Computer

Avinash Dash, Sumit Rout, Bikash K. Behera +1

It is well known that Grover's algorithm asymptotically transforms an equal superposition state into an eigenstate (of a given basis). Here, we demonstrate a verification algorithm…
