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…

Optimal discrimination of quantum sequences
Tathagata Gupta, Shayeef Murshid, Vincent Russo +1
A key concept of quantum information theory is that accessing information encoded in a quantum system requires us to discriminate between several possible states the system could b…
