Some measurements in quantum mechanics disturb each other. This has puzzled physicists
since the formulation of the theory, but only in recent decades has the incompatibility of …

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

Dense coding is the seminal example of how entanglement can boost qubit communication,
from sending one bit to sending two bits. This is made possible by projecting separate …

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 …

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 …

We explore the possibility of multiple usage of a single genuine entangled state by
considering a scenario consisting of three spin-1 2 particles shared between Alice, Bob, 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 …

A random access code (RAC) is a strategy to encode a message into a shorter one in a way
that any bit of the original can still be recovered with nontrivial probability. Encoding with …

Quantum nonlocality offers a secure way to produce random numbers: Their unpredictability
is intrinsic and can be certified just by observing the statistic of the measurement outcomes …

Quantum communication is often investigated in scenarios where only the dimension of
Hilbert space is known. However, assigning a precise dimension is often an approximation …
