Correlations of fluctuations are the driving forces behind the dynamics and thermodynamics
in quantum many-body systems. For qubits embedded in a quantum bath, the correlations in …

We investigate electron transport through a double dot Aharonov-Bohm interferometer
coupled to a heat bath, which provides not only a dephasing source but also non-Markovian …

Conservation principles are essential to describe and quantify dynamical processes in all
areas of physics. Classically, a conservation law holds because the description of reality can …

Bell's theorem renders quantum correlations distinct from those of any local-realistic model.
Although being stronger than classical correlations, quantum correlations are limited by the …

We introduce an experimental test for ruling out classical explanations for the statistics
obtained when measuring arbitrary observables at arbitrary times using individual detectors …

A famous theorem of Hilbert from 1888 states that a positive semidefinite (psd) real form is a
sum of squares (sos) of real forms if and only if $ n= 2$ or $ d= 1$ or $(n, 2d)=(3, 4) $, where …

The nonsymmetrized current noise is crucial for the analysis of light emission in
nanojunctions. The latter represent non-classical photon emitters whose description …

We discuss quantum mechanical detection models in the weak limit in the context of
conservation laws of physical quantities. In particular, we analyze what kind of system …

Conservation principles are essential to describe and quantify classical and quantum
mechanical processes. Classically, the conservation holds objectively because the …

A quantum computer is a special kind of computer that perform its tasks by leveraging the
laws of quantum mechanics. For particular classes of problems, such devices are expected …
