Abstract

We are currently developing a long-baseline quantum network in Long Island, New York. We have communicated quantum memories over a 158km network between Stony Brook and Brookhaven. Here we present the quantum enabling tools necessary to construct a quantum capable internet.

Observations on a 158km-long quantum internet testbed connecting room-temperature quantum memories

First-generation long-distance quantum repeater networks require quantum memories capable of interfacing with telecom photons to perform quantum-interference-mediated entanglement generation operations. The ability to demonstrate these interconnections using real-life fiber connections in a long-distance setting is paramount to realize a scalable quantum internet.

A long-distance quantum-capable internet testbed

Building a Quantum Internet requires the development of innovative quantum-enabling networking architectures that integrate advanced communication systems with long-distance quantum communication hardware. Here, we present the implementation of a quantum-enabled internet prototype using a novel physics-centric stack-based quantum network paradigm to govern the dynamics of multiple light-matter Hamiltonians across distant nodes. We demonstrate this concept using a deployed large-scale intercity quantum network connecting laboratories at Stony Brook University and the Brookhaven National Laboratory. This network facilitates a fundamental long-distance quantum network service -that of high-visibility Hong-Ou-Mandel interference of telecom quantum states generated in two independent, telecom-compatible quantum light-matter interfaces separated by a distance of 158 km.

We present a first-generation long-distance quantum internet testbed that utilizes quantum memories to communicate quantum information across an intercity fiber infrastructure. We have observed Hong-Ou-Mandel interference between telecom photons produced in two independent room temperature quantum memories separated by a distance of 158 km.
