Tackling decoherence via weak quantum measurement and quantum measurement revers
Abstract: Decoherence, often caused by unavoidable coupling with the environment, leads to degradation of quantum coherence. For a multipartite quantum system, decoherence leads to degradation of ent...

Qunatum Journal Club: Enhanced Quantum Interface with Collective Ion-Cavity Coup
Abstract: We prepare a maximally entangled state of two ions and couple both ions to the mode of an optical cavity. The phase of the entangled state determines the collective interaction of the ions ...

Fundamental limitations for quantum and nano thermodynamics
Abstract: The relationship between thermodynamics and statistical physics is valid in the thermodynamic limit when the number of particles becomes very large. Here we study thermodynamics in the oppo...
