The QUANT-NET Testbed Development and Preliminary Results

Le résumé fourni par la source

The U.S. Department of Energy (DOE) is currently supporting Berkeley Lab (LBNL), UC Berkeley (UCB), Caltech, and the University of Innsbruck in constructing a testbed for quantum networking technologies (QUANT-NET). The goal is to establish this network between two sites, LBNL and UCB, connected with an entanglement swapping substrate over ~5 km optical fiber and managed by a quantum network protocol stack. On top of this entanglement swapping substrate the research team will implement the most basic building blocks of distributed quantum computing and quantum repeaters by teleporting a controlled-NOT gate between two far trapped-ion quantum computation nodes. This paper presents QUANT-NET, its design, key technologies, and preliminary results. The preliminary results are focused on the QUANT-NET testbed infrastructure control, measurement, and characterization, which includes the implementation of a Hong-Ou-Mandel (HOM) interferometer across the fiber links, and the development and deployment of link polarization drift control in the testbed. These implementations are critical to our next stage research activities.
