Efficient entanglement-assisted discrimination of a class of many-copy indistinguishable sets
Abhay Srivastav, Saronath Halder
We explore entanglement as a resource to distinguish locally indistinguishable orthogonal quantum states. Specifically, we consider sets which contain states from an unextendible p…
Quantum advantage in a unified scenario and secure detection of resources
Saronath Halder, Alexander Streltsov
Quantum resources may provide advantage over their classical counterparts. We say this as quantum advantage. Here we consider a single communication task to study different approac…
Unextendibility, uncompletability, and many-copy indistinguishable ensembles
Saronath Halder, Alexander Streltsov
In this work, we explore the notions unextendible product basis and uncompletability for operators which remain positive under partial transpose. Then, we analyze their connections…
Self-testing composite measurements and bound entangled state in a single quantum network
Shubhayan Sarkar, Chandan Datta, Saronath Halder +1
Within the quantum networks scenario we introduce a single scheme allowing to certify three different types of composite projective measurements acting on a three-qubit Hilbert spa…
Information locking and its resource efficient extraction
Suchetana Goswami, Saronath Halder
Locally indistinguishable states are useful to distribute information among spatially separated parties such that the information is locked. This implies that the parties are not a…
