Quantum correlation and quantum measurement are core issues in understanding the
quantum world. Revealing quantum correlations in microphysical systems through proper …

We examine the satisfaction of Bell criteria for single realizations of quantum systems. This is
possible via the joint noisy measurement of all observables involved in the Bell test. We …

Bell inequalities represent a milestone for contemporary physics, both for quantum
foundation investigations and technological applications (eg, quantum communication and …

Weak value amplification is crucial in quantum metrology because it enhances the detection
of subtle interactions between quantum entities. However, current weak value quantum …

Device-independent quantum key distribution (DI-QKD) leverages nonlocal correlations to
securely establish cryptographic keys between two honest parties while making minimal …

Quantum theory is notoriously counterintuitive, and yet remains entirely self-consistent when
applied universally. Here we uncover a new manifestation of its unusual consequences. We …

Quantum paradoxes show that the outcomes of different quantum measurements cannot be
described by a single measurement-independent reality. Any theoretical description of a …
