Physics - IQUIST Seminar

Abstract:

Quantum circuits provide a promising path for engineering tailored quantum systems from the ground up.  However, the strong light-matter interactions that enable high-fidelity gate operations and measurements in these circuits make it difficult to maintain good isolation of memories and simultaneously realize good connectivity. In this talk I will review ongoing efforts to achieve modular scaling using microwave photons as information carriers. In particular, I will focus on the use of nonlinear mixing in Josephson junctions to realize microwave photonic interconnects that allow connecting individual qubits and cavities on-demand. Recent experiments in this area have enabled the realization of prototypical quantum networks, and ongoing work shows great potential for achieving multi-node networks with high degrees of connectivity.
