Abstract
In analogy with electronic transistors, a single photon transistor is a device where the presence or absence of a single gate photon controls the propagation of a large number of signal photons [1, 2]. Such devices would represent a milestone in our ability to control light, but their realization is hampered by the weak interaction among photons. A promising route towards strong interactions at the single photon level consists of coupling propagating photons to individual atom- like systems [3-9]. The best realization of such a coupling has been achieved in the microwave regime where experiments have demonstrated an unprecedented control of the coupling between superconducting artificial atoms and microwave photons [10, 11]. In this letter we describe how to realize a single photon transistor based on existing superconducting technology. The resulting devices can be directly employed to efficiently detect individual itinerant microwave photons, and may find a range of applications within quantum information processing.Citation
