Operational Discriminability: From Noncontextuality Bounds to Bell Correlations
Seyed Arash Ghoreishi
We investigate discriminability from an operational and contextuality-oriented perspective using a two-copy comparison game based on SWAP-type measurements. The resulting score $D_…
The future of secure communications: device independence in quantum key distribution
Seyed Arash Ghoreishi, Giovanni Scala, Renato Renner +4
In the ever-evolving landscape of quantum cryptography, Device-independent Quantum Key Distribution (DI-QKD) stands out for its unique approach to ensuring security based not on th…
Multiple-shot labeling of quantum observables
Seyed Arash Ghoreishi, Nidhin Sudarsanan Ragini, Sk Sazim +1
Quantum labeling tasks ask one to recover the missing associations between classical outcome labels and the effects forming the POVM. We study labeling in the multiple-shot regime,…
Advantages of quantum communication revealed by the reexamination of hyperbit theory limitations
Giovanni Scala, Seyed Arash Ghoreishi, Marcin Pawłowski
Pawłowski and Winter's hyperbit theory, proposed in 2012, presented itself as an alternative to quantum theory, suggesting novel ways of redefining entanglement and classical commu…
Geometric Bloch Vector Solution to Minimum Error Discriminations of Mixed Qubit States
Mahdi Rouhbakhsh N., Seyed Arash Ghoreishi
We investigate minimum-error (ME) discrimination for mixed qubit states using a geometric approach. By analyzing positive operator-valued measure (POVM) solutions and introducing L…
Minimum-error discrimination of thermal states
Seyed Arash Ghoreishi, Mario Ziman
We study several variations of the question of minimum-error discrimination of thermal states. Besides of providing the optimal values for the probability of error, we also charact…
Parametrization of quantum states and the quantum state discrimination problem
Seyed Arash Ghoreishi, Seyed Javad Akhtarshenas, Mohsen Sarbishaei
A discrimination problem consists of linearly independent pure quantum states and the corresponding occurrence probabilities . To any such problem…
