Interference Effects in a Tunable Quantum Point Contact Integrated with an Electronic Cavity
Year: 2017
Type: article
Abstract: Quantum information processing is seen as the key to technological advancement, but an easily accessible and scalable scheme is required to fulfill its potential. In this regard, the authors investigate electron transport through an integrated quantum device, consisting of a quantum point contact coupled to a tunable electronic cavity. They observe anomalous interference features due to coupling between the two systems; this is related to the well-known Fano effect. Their prototype device could offer a step toward the quantum analog of amplitude modulation, or phase modulation.
