Quantum work beyond classical (commuting) limits
Sumit Rout, Aravinth Balaji Ravichandran, PaweÅ 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, PaweÅ 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…
