- Abstract: It is well known that when two or more quantum measurements suffer from
imperfections they may lose their incompatibility. For a quantum system of
finite dimension d we study the incompatibility of all projective measurements
subjected to white noise and loss. We derive a necessary and sufficient
conditions for this set of measurements to becomes compatible in terms of their
visibility $p$ and efficiency $\eta$.

We investigate the measurement incompatibility of continuous-variable systems with infinite-dimensional Hilbert spaces under the influence of pure losses.
We show that loss channels with transmissivities less than $1/n$ make any set of $n$ measurements compatible.
We design a set of measurements that remains incompatible even under extreme losses, where the number of measurements in the set increases with the amount of loss.

We prove that any set of incompatible measurements on qubits leads to a violation of a suitable Bell inequality in a multiparticle scenario.
Our results imply that measurement incompatibility for qubits can always be certified in a device-independent manner.

Local quantum measurements do not simply disentangle degrees of freedom, but may actually strengthen the entanglement in the system.
This paper explores how a finite density of local measurement modifies a given state's entanglement structure.

Heisenberg argued that measurements irreversibly alter the state of the system on which they are acting, causing an irreducible disturbance on subsequent measurements.
This article shows that measurement incompatibility is indeed a sufficient condition for irreversibility of measurement disturbance.
However, we exhibit a toy theory, termed the minimal classical theory (MCT), that is a counterexample for the converse implication.

We study Bell inequalities where measurements of different parties can have overlap.
This allows to accommodate problems in quantum information.
The scenarios considered show an interesting behaviour with respect to Hilbert space dimension, overlap, and symmetry.

Entanglement -- the coherent correlations between parties in a quantum system -- is well-understood and quantifiable.
Despite the utility of such systems, methods for quantifying high-dimensional entanglement are more limited and experimentally challenging.
We present a novel certification method whose measurement requirements scale linearly with dimension subsystem.

The heart of our setup is the novel soliton Josephson Junction (SJJ) system providing the formation of the quantum probe.
We illustrate that such states are close to the optimal ones even with moderate losses.
