Quantum-Classical Coexistence Network Tomography
Xuchuang Wang, Joseph C. Chapman, Aneesh Ramaswamy +5
Quantum-classical coexistence networks (QCNs) share optical fiber between quantum and classical signals via wavelength-division multiplexing, offering a practical path to quantum c…
Analysis of polarization drift of optical signals over deployed aerial-inground fiber connections
Aneesh Ramaswamy, Nageswara S. V. Rao, Joseph C. Chapman +1
Polarization measurements of a classical 1550-nm signal are collected and analyzed on 15-km hybrid aerial-inground fiber connections over 11 months. The spectral area and spectral…
Zero-added-loss entanglement multiplexing using time-bin spectral shearing
Joseph C. Chapman, Muneer Alshowkan, Jack Postlewaite +2
High-quality quantum communications that enable important capabilities, such as distributed quantum computing and sensing, will require quantum repeaters for providing high-quality…
Continuous Automatic Polarization Channel Stabilization from Heterodyne Detection of Coexisting Dim Reference Signals
Joseph C. Chapman, Muneer Alshowkan, Kazi Reaz +2
Quantum networking continues to encode information in polarization states due to ease and precision. The variable environmental polarization transformations induced by deployed fib…
