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…
In situ quantum verification of polarization-stabilized optical channels
Matthew L. Stevens, Noah I. Wasserbeck, Zachary Goisman +8
The active stabilization of polarization channels is a task of growing importance as quantum networks move to deployed demonstrations over existing fiber infrastructure. However, t…
Entanglement-based quantum digital signatures over deployed campus network
Joseph C. Chapman, Muneer Alshowkan, Bing Qi +1
The quantum digital signature protocol offers a replacement for most aspects of public-key digital signatures ubiquitous in today's digital world. A major advantage of a quantum-di…
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…
