DOI: 10.1103/physrevb.100.195125
Abstract: Generative modeling with machine learning has provided a new perspective on the data-driven task of reconstructing quantum states from a set of qubit measurements. As increasingly large experimental quantum devices are built in laboratories, the… read more here.

DOI: 10.1103/physrevlett.129.150602
Abstract: The third law of thermodynamics, also known as the Nernst unattainability principle, puts a fundamental bound on how close a system, whether classical or quantum, can be cooled to a temperature near to absolute zero.… read more here.

DOI: 10.1134/s1995080218010109
Abstract: We introduce a spin polarization-scaling map for spin-j particles, whose physical meaning is the decrease of spin polarization along three mutually orthogonal axes. We find conditions on three scaling parameters under which the map is… read more here.
