Quantum Photonics for Quantum Machine Learning, Secure Computing, and Precision Measurements

Datum: 23.06.2021
Uhrzeit: 11:30
Vortragende(r): Prof. Walther
Faculty of Physics, University of Vienna, Austria
Ort: Zoom meeting
Gastgeber: Ignacio Cirac

This talk presents recent experimental demonstrations that use integrated nanophotonic processors for various quantum computations such as quantum machine learning and in particular reinforcement learning, where agents interact with environments by exchanging signals via a communication channel. We show that this exchange allows boosting the learning of the agent. [mehr]

Ort: Herbert Walther Lecture Hall, MPI für Quantenoptik, Garching
Gastgeber: Ignacio Cirac

Randomized measurements are a technique to probe many-body quantum states beyond familiar, low-order observables. In this talk, I introduce the technique using the example of measuring the second-order Rényi entropy in a trapped ion quantum simulator. [mehr]
