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

Of late, there has been an upsurge of interest in studying the sequential sharing of various
forms of quantum correlations, viz., nonlocality, preparation contextuality, coherence, and …

Unsharp measurements are widely seen as the key resource for recycling the nonlocality of
an entangled state shared between several sequential observers. Contrasting this, we here …

The Bell nonlocality is closely related to the foundations of quantum physics and has
significant applications to security questions in quantum key distributions. In recent years …

The question of whether complex numbers play a fundamental role in quantum theory has
been debated since the inception of quantum mechanics. Recently, a feasible proposal to …

Quantum network nonlocality sharing provides a unique perspective for constructing large-
scale quantum networks and holds promise for numerous potential applications. In this …

Semi-device-independent certification of an unsharp instrument has recently been
demonstrated (2019 New J. Phys. 21 083034) based on the sequential sharing of quantum …

Based on the quantum violation of the bipartite Bell inequality, it has been established that
the sharing of nonlocality can be demonstrated for at most two sequential observers at one …

Quantum nonlocality is a significant feature in quantum information theory, prompting recent
investigations into the potential reuse of postmeasurement states to uncover nonlocality …

Quantum correlation is a key resource for a variety of quantum information processing and
communication tasks, the efficient utilization of which has been a longstanding concern, and …
