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…
Global versus Local Discrimination of Locally Implementable Multipartite Unitaries
Satyaki Manna, Sneha Suresh, Anandamay Das Bhowmik +1
We study single-shot distinguishability of locally implementable multipartite unitaries under Local Operations and Classical Communication (LOCC) and global operations. As unitary…
Limitation of maximally entangled probes for single-shot distinguishability of unitaries
Satyaki Manna, Anandamay Das Bhowmik, Debashis Saha
There have been many instances where the maximally entangled state as a probe acts better than the product and the non-maximally entangled states in the task of distinguishing quan…
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…
Limits of Classical correlations and Quantum advantages under (Anti-)Distinguishability constraints in Multipartite Communication
Ankush Pandit, Soumyabrata Hazra, Satyaki Manna +2
We consider communication scenarios with multiple senders and a single receiver. Focusing on communication tasks where the distinguishability or antidistinguishability of the sende…
