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 Covert Quantum Computing
Evan J. D. Anderson, Kaushik Datta, Boulat A. Bash
As quantum computers become available through multi-tenant cloud platforms, ensuring privacy against adversaries sharing the same quantum processing unit becomes critical. We intro…
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 RozpÄdek +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…
