Quantum Advantage in Shared Randomness Processing

2020 · arXiv (Cornell University)

Randomness appears both in classical stochastic physics and in quantum mechanics. A number of communication models and other information protocols entail sharing randomness among distant parties. Here we report a computational scenario of shared randomness …

Hierarchical activation of quantum nonlocality: Stronger than local indistinguishability

2023 · Physical Review A

The quantum state discrimination primitive becomes highly nontrivial in the limited measurement setting and leads to different classes of impossibility, viz., indistinguishability, unmarkability, irreducibility, etc. These phenomena, often referred to as another nonlocal aspect of …
