[Aspuru-Guzik Group List] ITAMP seminar - B. Vermersch, IQOQI Innsbruck (tomorrow, Friday 28th, 10:30am)

ITAMP Seminar (Note the unusual time and place) Speaker: Benoit Vermersch (IQOQI Innsbruck) Date: Friday, July 28th Time: 10:30am-12:00pm Location: Pratt conference room @ Center for Astrophysics (60 Garden Street) Title: Measuring entanglement in many-body quantum systems. Abstract: In the first part of my talk, I will show how to measure the entanglement spectrum of ground states of generic Hamiltonians based on the direct engineering of the entanglement Hamiltonian [1]. Our method, based on the Bisognano-Wichmann theorem, allows to measure the entanglement spectrum via spectroscopy techniques. I will provide numerical examples to support this result and give examples of AMO implementations of entanglement Hamiltonians. In the second part of my talk, I will present a method to measure Renyi entropies using random quenches. I will illustrate our approach in the context of 2d Hubbard (ultracold atoms) and Quantum Ising (Rydberg atoms, trapped ions) models.
