Arbitrarily many independent observers can share the nonlocality of a single maximally entangled qubit pair
Alice and Bob each have half of a pair of entangled qubits. Bob measures his half and then
passes his qubit to a second Bob who measures again and so on. The goal is to maximize …

Recycling qubits for the generation of Bell nonlocality between independent sequential observers
There is currently much interest in the recycling of entangled systems, for use in quantum
information protocols by sequential observers. In this work, we study the sequential …

Facets of bipartite nonlocality sharing by multiple observers via sequential measurements
Recently, it has been shown that at most two observers (Bobs) can sequentially demonstrate
bipartite nonlocality with a spatially separated single observer (Alice) invoking a scenario …

Genuine Einstein-Podolsky-Rosen steering of three-qubit states by multiple sequential observers
We investigate the possibility of multiple uses of a single copy of a three-qubit state for
detecting genuine tripartite Einstein-Podolsky-Rosen (EPR) steering. A pure three-qubit …

Limits on sequential sharing of nonlocal advantage of quantum coherence
Sequential sharing of nonlocal correlation is inherently related to its application. We address
the question as to how many observers can share the nonlocal advantage of quantum …

Projective measurements are sufficient for recycling nonlocality
A Steffinlongo, A Tavakoli - Physical Review Letters, 2022 - APS
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 …
