      abstract     = {The Faraday-effect circulator was invented in the 1950's,
                      based on some fundamental theoretical insights about the
                      role of nonreciprocity in transmission systems. These
                      Faraday devices are used successfully at both optical and at
                      microwave frequencies; the latter have a unique and
                      essential role in making solid-state quantum computing work.
                      Also in the 1950's, microwave circulators based on the Hall
                      effect,were also considered. It was "proved" then that a
                      Hall bar cannot make a good gyrator (a close cousin to the
                      circulator). This proof is flawed, and we have shown that
                      good gyrators are possible in the quantum Hall regime, if
                      the device is contacted capacitively. We predict that the
                      resulting Hall circulator can be much more miniaturized than
                      the Faraday kind, and I will discuss some recent preliminary
                      experimental efforts in this direction. I will discuss the
                      relation of this device functionality to the physics of
                      chiral edge magnetoplasmons in the Hall conductor.},
