SUMMARY:Séminaire du LPTMS : Benoît Vermersch (LPMMC Grenoble) - LPTMS (1
 00% online seminar) - 16 Mar 21 11:00
DESCRIPTION:Probing mixed-state\, symmetry-resolved\, entanglement with ran
 domized measurements\nBenoît Vermersch (LPMMC Grenoble)\nOnline seminar -
 -- ZOOM Meeting ID: 970 5162 7987 -- Password: ask L. Mazza and D. Petrov 
 --\n\nRecently\, protocols based on statistical correlations of randomized
  measurements have been introduced to probe entanglement in synthetic quan
 tum systems. This includes protocols to access Renyi entropies\, many-body
  state fidelities\, out-of-time-ordered correlators (OTOCs) and topologica
 l invariants\, etc. In this seminar\, I will first give a tutorial introdu
 ction to randomized measurements. Then\, I will present our protocol for d
 etecting and quantifying mixed-state entanglement in the framework of the 
 positive-partial-transpose condition (PPT). Finally\, I will discuss symme
 try-resolved entanglement in synthetic quantum systems\, and present a uni
 versal mechanism of purification and entanglement creation of many-body qu
 antum states. In all parts of my talk\, I will show experimental results o
 btained in the Innsbruck's trapped ion quantum simulator.
