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…

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…

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 quantum-secure covert communication over bosonic channels

Michael S. Bullock, Christos N. Gagatsos, Saikat Guha +1

We investigate the fundamental limit of quantum-secure covert communication over the lossy thermal noise bosonic channel, the quantum-mechanical model underlying many practical cha…

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…
