High-Fidelity Hot Gates for Generic Spin-Resonator Systems (Dr. M. Schütz)

Date: Mar 29, 2017
Time: 11:30 AM - 12:30 PM (Local Time Germany)
Speaker: Dr. Martin Schütz
Harvard University, Department of Physics, USA
Room: Herbert Walther Lecture Hall
Host: MPQ, Theory Division

We propose and analyze a high-fidelity hot gate for generic spin-resonator systems which allows for coherent spin-spin coupling, in the presence of a thermally populated resonator mode. [more]

The Density Matrix Renormalisation Group when applied to matrix-product states is the method of choice for ground-state search on one-dimensional systems and still highly competitive even in unfavourable circumstances, such as critical systems and higher dimensions. [more]

Quantum optics with semiconductor quantum dots (Prof. P. Senellart-Mardon)

Room: Herbert Walther Lecture Hall
Host: MPQ, Quantum Dynamics Division

Today, optical quantum technologies are limited both by the low efficiency of heralded single-photon sources and by the probabilistic operation of two-photon gates. [more]
