  In this work, we performed magnetoresistance measurement in a hybrid system
consisting of an arc-shaped quantum point contact (QPC) and a flat, rectangular
QPC, both of which together form an electronic cavity between them. The results
highlight a transition between collimation-induced resistance dip to a
magnetoresistance peak as the strength of coupling between the QPC and the
electronic cavity was increased. The initial results show the promise of hybrid
quantum system for future quantum technologies.
