Public Quantum Network: Dealing with People and Polarization Qubits over Optical Fiber
Abstract: Quantum networks are under development worldwide to advance cryptographic systems, improve metrology, and propel quantum computing systems. However, these networks are not yet broadly accessible to the public. We have developed a publicly accessible quantum network node in Urbana-Champaign to bridge this gap. By introducing this cutting-edge technology to the public, we aim to foster public engagement in quantum experiments and cultivate interest and early exposure to quantum technology. By utilizing the polarization-based entanglement source located at the University of Illinois Urbana-Champaign, the public can select measurement bases and perform their own CHSH inequality measurements. Realizing this goal entails various engineering and scientific challenges, such as optical loss and polarization drift. This presentation will discuss the establishment of the first public quantum network node and the possible solutions to overcome these challenges.
