Sidewall-Poled Nanophotonic Lithium Niobate with Bidirectional Characterization
Aditya Tripathi, Michael S. Bullock, Parash Thapalia +10
Accurate characterization of integrated nonlinear photonic devices is often limited by unknown facet-coupling losses and fabrication-induced non-uniformities, leading to systematic…
Covert Signaling for Communication and Sensing over the Bosonic Channels
Tianrui Tan, Evan J. D. Anderson, Michael S. Bullock +1
Preventing signal detection in communication and active sensing requires careful control of transmission power. In fact, the square-root laws (SRL) for covert classical and quantum…
Toward Practical Two-Way Covert Communication
Paul N. Fessatidis, Wyatt Wallis, Tae E. Cooper +6
We study two-way covert communication schemes, where information is transmitted by passively modulating a reflected signal back to the source. We consider optical systems, describe…
Rethinking Quantum Networking with Advances in Fiber Technology
Prateek Mantri, Michael S. Bullock, Aditya Tripathi +3
Recent comparisons of quantum repeater protocols have highlighted the strong near-term potential of multiplexed two-way architectures for long-distance quantum communication. At th…
Experimental Validation of Provably Covert Communication Using Software-Defined Radio
Rohan Bali, Trevor E. Bailey, Michael S. Bullock +1
The fundamental information-theoretic limits of covert, or low probability of detection/intercept (LPD/LPI), communication have been extensively studied for over a decade, resultin…
Covert Entanglement Generation over Bosonic Channels
Evan J. D. Anderson, Michael S. Bullock, Ohad Kimelfeld +4
We explore covert entanglement generation over the lossy thermal-noise bosonic channel, which is a quantum-mechanical model of many practical settings, including optical, microwave…
