DOI: 10.1002/adfm.201904784
Abstract: Effective manipulation of phonons is crucial to modern energy‐information science and technologies but limited by the charge neutral and spinless nature of phonons. Recently, novel quantum concepts, including Berry phase, topology, and pseudospin, are introduced… read more here.

DOI: 10.1007/s00006-018-0904-5
Abstract: Localized states in relativistic quantum field theories are usually considered as problematic, because of their seemingly strange (noncovariant) behavior under Lorentz transformations, and because they can spread faster than light. We point out that a… read more here.

DOI: 10.1088/1367-2630/ab193d
Abstract: We present protocols to generate arbitrary photonic graph states from quantum emitters that are in principle deterministic. We focus primarily on two-dimensional cluster states of arbitrary size due to their importance for measurement-based quantum computing.… read more here.

DOI: 10.1103/physreva.104.l050402
Abstract: We find that a bipartite quantum state is entangled if and only if it is quantum coherent with respect to complete bases of states in the corresponding system that are distinguishable under local quantum operations… read more here.

DOI: 10.1134/s1995080218060033
Abstract: In this paper some examples of sequences of compositions of n independent equally distributed random semigroups in the form of a shift operator generating coherent states in quantum optics have been studied. Representation of averaged… read more here.

DOI: 10.3390/e24111509
Abstract: The framework of Quantum Darwinism strives at characterizing the quantum-to-classical transition by introducing the concept of redundancy of information—as measured by Mutual Information—that a set of observers would acquire on the state of a physical… read more here.
