Contextuality-based quantum key distribution with deterministic single-photon sources
Yu Meng, Debashis Saha, Mikkel Thorbjørn Mikkelsen +7
Photons are central to quantum technologies, with photonic qubits offering a promising platform for quantum communication. Semiconductor quantum dots stand out for their ability to…
Maximally epistemic models cannot explain gambling with two qubits
Sagnik Ray, Anubhav Chaturvedi, Debashis Saha
We investigate the minimal proof for ruling out maximally epistemic interpretations of quantum theory, in which the indistinguishable nature of two quantum states is fully expl…
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…
Communication scenario enables robust self-testing of n-party Greenberger-Horne-Zeilinger basis measurements
Barnik Bhaumik, Sagnik Ray, Debashis Saha
Entangled basis measurements play a crucial role in distributing quantum entanglement between parties across a quantum network. In this work, we adopt a semi-device-independent app…
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…
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…
Supersinglets can be self-tested with perfect quantum strategies
Debashis Saha, Adán Cabello
Supersinglets are states of spin-zero of particles of levels. They are invariant under unitary transformations of the form and have applications in me…
