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…
Local strategies are pretty good at computing Boolean properties of quantum sequences
Tathagata Gupta, Ankith Mohan, Shayeef Murshid +3
Quantum memory is a scarce and costly resource, yet little is known about which learning tasks remain feasible under severe memory constraints. We study the problem of computing gl…
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…
