Tunable directionality can be achieved by applying external magnetic fields that modify optical selection rules, by using nonlinear effects, or interactions with vibrations. However, these approaches are less suitable to control microwave photon propagation inside integrated superconducting quantum devices. Here, we demonstrate on-demand tunable directional scattering based on two periodically modulated transmon qubits coupled to a transmission line at a fixed distance. By changing the relative phase between the modulation tones, we realize unidirectional forward or backward photon scattering. Such an in-situ switchable mirror represents a versatile tool for intra- and inter-chip microwave photonic processors. In the future, a lattice of qubits can be used to realize topological circuits that exhibit strong nonreciprocity or chirality."}],"doi":"10.1038/s41467-023-38761-6","publication":"Nature Communications","volume":14,"publisher":"Springer Nature","publication_identifier":{"eissn":["2041-1723"]},"type":"journal_article","oa_version":"Published Version","scopus_import":"1","acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"NanoFab"}],"publication_status":"published","article_type":"original","file":[{"relation":"main_file","date_updated":"2023-06-06T07:31:20Z","access_level":"open_access","success":1,"checksum":"a857df40f0882859c48a1ff1e2001ec2","creator":"dernst","date_created":"2023-06-06T07:31:20Z","content_type":"application/pdf","file_id":"13123","file_size":1654389,"file_name":"2023_NaturePhysics_Redchenko.pdf"}],"ec_funded":1,"date_updated":"2023-08-02T06:10:26Z","quality_controlled":"1","language":[{"iso":"eng"}],"project":[{"grant_number":"F07105","_id":"26927A52-B435-11E9-9278-68D0E5697425","name":"Integrating superconducting quantum circuits","call_identifier":"FWF"},{"call_identifier":"H2020","name":"A Fiber Optic Transceiver for Superconducting Qubits","_id":"26336814-B435-11E9-9278-68D0E5697425","grant_number":"758053"},{"_id":"26B354CA-B435-11E9-9278-68D0E5697425","name":"Controllable Collective States of Superconducting Qubit Ensembles"},{"_id":"eb9b30ac-77a9-11ec-83b8-871f581d53d2","name":"Protected states of quantum matter"}],"month":"05","intvolume":"        14","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","external_id":{"isi":["001001099700002"],"arxiv":["2205.03293"]},"acknowledgement":"The authors thank W.D.
