Nonlocal Measurements via Quantum Erasure [PDF]

Physical Review Letters, 2016
Non-local observables play an important role in quantum theory, from Bell inequalities and various post-selection paradoxes to quantum error correction codes. Instantaneous measurement of these observables is known to be a difficult problem, especially when the measurements are projective.

Simultaneous sudden change in the exact values of geometric quantum discord and measurement induced nonlocality [PDF]

Iranian Journal of Astronomy and Astrophysics, 2018
Recent studies show that two completely distinct fields as quantum information and string theory realization can be related and share some of the same properties.

Postquantum steering [PDF]

, 2015
The discovery of postquantum nonlocality, i.e., the existence of nonlocal correlations that are stronger than any quantum correlations but nevertheless consistent with the no-signaling principle, has deepened our understanding of the foundations of ...

Quantum analogues of Hardy's nonlocality paradox [PDF]

, 2011
Hardy's nonlocality is a "nonlocality proof without inequalities": it exemplifies that quantum correlations can be qualitatively stronger than classical correlations.

Exploring the Limits of Quantum Nonlocality with Entangled Photons

Physical Review X, 2015
Nonlocality is arguably among the most counterintuitive phenomena predicted by quantum theory. In recent years, the development of an abstract theory of nonlocality has brought a much deeper understanding of the subject, revealing a rich and complex ...

Network quantum steering enables randomness certification without seed randomness [PDF]

Quantum
Quantum networks with multiple sources allow the observation of quantum nonlocality without inputs. Consequently, the incompatibility of measurements is not a necessity for observing quantum nonlocality when one has access to multiple quantum sources ...

Discriminating quantum correlations with networking quantum teleportation

Physical Review Research, 2020
The Bell inequality, and its substantial experimental violation, offers a seminal paradigm for showing that the world is not in fact locally realistic.

All quantum states useful for teleportation are nonlocal resources [PDF]

, 2012
Understanding the relation between the different forms of inseparability in quantum mechanics is a longstanding problem in the foundations of quantum theory and has implications for quantum information processing.
