Infrastructure
The infrastructure at the core of the research aims of this Center is the quantum repeater network of quantum light-matter interfaces that already connects several locations within and between BNL and Stony Brook University, using available fiber quantum links provided by ESnet and the Stony Brook Department of Information Technology (DoIT).
We have two quantum local area networks (QLANs) currently implemented. The first utilizes an existing optical fiber infrastructure and has deployed entanglement sources and quantum memories in several buildings on the BNL campus, with fibers used to quantum connect the Physics and Instrumentation buildings with the Scientific Data and Computation Center (SDCC). As mentioned earlier, a similar QLAN was developed in parallel on the Stony Brook campus (connecting Physics, Communications Engineering, the Basic Science tower, and CEWIT). With the quantum communication channels in place, we will use the photonic entanglement sources to simultaneously store and retrieve quantum correlations in four quantum memories in both locations. This quantum repeater network will be based on scalable room-temperature quantum memories, bridged to work with entangled photons at telecom wavelengths.
By using quantum memories to enhance the swapping of the polarization entanglement of pairs of flying photons, our implementation will take a significant leap in quantum communication by distributing entanglement over long distances without detrimental losses. The recent technological developments needed to achieve high-fidelity quantum operation at room temperature are a unique strength and will be a focus of our Center’s activities. With the support of the Center’s members, we will expand the infrastructure in functionality, size, and number of devices, aiming to demonstrate full potential of quantum repeaters for relaying continuous and discrete variables and their use to enhance current complex data communication systems.
