Entanglement-assisted Hamiltonian dynamics learning

Ayaka Usui, Guillermo Abad-López, Hari krishnan SV +2

Approximating the dynamics given by a complex many-body Hamiltonian with a simpler effective model lies at the interface of quantum Hamiltonian learning and quantum simulation. In…

Local Inaccessibility of Random Classical Information and Their Implications in the Change Point Problem

Snehasish Roy Chowdhury, Subhendu B. Ghosh, Tathagata Gupta +4

Discrimination of quantum states under local operations and classical communication (LOCC) is an intriguing question in the context of local retrieval of classical information, enc…

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…

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…
