DESCRIPTION:Speaker: Andrés Rosario Hamann\nhosted by Johannes Fink\nAbstr
 act: Nonreciprocal devices are a key element for signal routing and noise 
 isolation. The latest developments in the field of quantum technologies ha
 ve boosted the demand for a new generation of miniaturized and low-loss no
 nreciprocal components. In this talk\, I will present our results on how t
 o use a pair of tunable superconducting artificial atoms embedded in a rec
 tangular waveguide to experimentally realize a minimal\, passive\, nonreci
 procal device. Taking advantage of the quantum nonlinear behavior of super
 conducting qubits\, we achieve nonreciprocal transmission through the wave
 guide in a wide range of powers. Our results are consistent with theoretic
 al modeling showing that nonreciprocity is associated with the population 
 of the two-qubit nonlocal entangled quasi-dark state\, which responds asym
 metrically to incident fields from opposing directions. Additionally\, our
  waveguide QED implementation allows us to explore other interesting pheno
 mena\, such as atom-photon bound states and entanglement stabilization.
