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…
Quantum nonlocality without entanglement and state discrimination measures
Shayeef Murshid, Tathagata Gupta, Vincent Russo +1
An ensemble of product states is said to exhibit "quantum nonlocality without entanglement" if it cannot be optimally discriminated using local operations and classical communicati…
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…
Locally distinguishing a maximally entangled basis using shared entanglement
Somshubhro Bandyopadhyay, Vincent Russo
We consider the problem of distinguishing between the elements of a bipartite maximally entangled orthonormal basis using local operations and classical communication (LOCC) and a…
Unambiguous discrimination of sequences of quantum states
Tathagata Gupta, Shayeef Murshid, Somshubhro Bandyopadhyay
We consider the problem of determining the state of an unknown quantum sequence without error. The elements of the given sequence are drawn with equal probability from a known set…
Channel assisted noise propagation in a two-step cascade
Mintu Nandi, Sudip Chattopadhyay, Somshubhro Bandyopadhyay +1
Signal propagation in biochemical networks is characterized by the inherent randomness in gene expression and fluctuations of the environmental components, commonly known as intrin…
