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…
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…
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…
Achievability of Covert Quantum Communication
Evan J. D. Anderson, Michael S. Bullock, Filip Rozpędek +1
We explore covert communication of qubits over an arbitrary quantum channel. Covert communication conceals the transmissions in the channel noise, ensuring that an adversary is una…
Linear optics and photodetection achieve near-optimal unambiguous coherent state discrimination
Jasminder S. Sidhu, Michael S. Bullock, Saikat Guha +1
Coherent states of the quantum electromagnetic field, the quantum description of ideal laser light, are prime candidates as information carriers for optical communications. A large…
Covert Capacity of Bosonic Channels
Christos N. Gagatsos, Michael S. Bullock, Boulat A. Bash
We investigate the quantum-secure covert-communication capabilities of lossy thermal-noise bosonic channels, the quantum-mechanical model for many practical channels. We determine…
Fundamental Limits of Covert Communication over Classical-Quantum Channels
Michael S. Bullock, Azadeh Sheikholeslami, Mehrdad Tahmasbi +3
We investigate covert communication over general memoryless classical-quantum channels with fixed finite-size input alphabets. We show that the square root law (SRL) governs covert…
