Quantum hypothesis testing of non-mixed-unitarity: A multifaceted hierarchy of quantum channel discrimination
Pratik Ghosal, Pritam Halder, Ayan Patra +2
Given multiple uses of an unknown quantum channel, we determine whether it is a specified non-mixed-unitary channel or belongs to the set of mixed-unitary channels. Formulating thi…
Local state antimarking : Nonlocality without entanglement
Biswadeep Chatterjee, Tathagata Gupta, Pratik Ghosal +1
A set of quantum states is said to be antidistinguishable if, upon being given a randomly chosen state from the set, it is possible to exclude with certainty a state that was defin…
Quantum state exclusion with many copies
Debanjan Roy, Tathagata Gupta, Pratik Ghosal +2
Quantum state exclusion is the task of identifying at least one state from a known set that was not used in the preparation of a quantum system. A set of quantum states is said to…
