Topology-independent quantum advantage in communication networks
Ankush Pandit, V. N. S. Meghanath Ashtakala, Leon George Padayatty +1
Quantum communication can outperform classical communication in a variety of information-processing tasks, but such advantages are typically established for a fixed communication n…
Self-testing ideal quantum measurements
Debashis Saha, Zhen-Peng Xu, Adán Cabello
A fundamental prediction of quantum mechanics is that observables can be measured through ideal measurements, that is, measurements that give the same outcome when repeated and do…
Nonlocality without entanglement for multipartite quantum measurements
Satyaki Manna, Debashis Saha
We show that a pair of two-qubit product measurements can be perfectly distinguished when accessed jointly, yet cannot be perfectly distinguished when their local components are di…
Semi-Device-Independent Quantum Key Distribution from Operational Assumptions
Anubhav Chaturvedi, Giuseppe Viola, Ekta Panwar +2
Semi-device-independent quantum key distribution leaves the measurement devices uncharacterized while placing a trusted assumption on Alice's source. We formulate this source assum…
Genuine certification of incompatible quantum instruments through sequential communication tasks
Arindam Mitra, Satyaki Manna, Debashis Saha
Quantum instruments constitute the general description of quantum dynamics, encompassing both quantum measurements and quantum channels as special cases. Consequently, the incompat…
Entanglement assisted communication complexity measured by distinguishability
Satyaki Manna, Ankush Pandit, Anubhav Chaturvedi +1
We investigate the quantum advantage that can arise in typical two-party communication scenarios, where the sender and the receiver are allowed to share prior correlations. Focusin…
