a Resistance of the device as a function of the phase bias applied on the SQUID and the bias current in the presence of an in-plane field along the y direction at By = 50 mT, By = 200 mT and By = 350 mT. \({V}_{\rm{g}}^{1}\) is set to −2 V and \({V}_{\rm{g}}^{2}\) to −4.5 V resulting in \({I}_{\rm{c}}^{1}\,\approx \,4{I}_{\rm{c}}^{2}\). The oscillation of the critical current present a visible forward tilt at 50 and 200 mT absent at 350 mT. b Evolution of the transparency of JJ2 as a function of the in-plane field By as determined from fitting the SQUID oscillation at different gate and fields (see “Methods”). The error bars correspond to typical variations observed across different similar data sets.
