Joint Communication and Sensing with Bipartite Entanglement over Bosonic Channels
Tuna ErdoÄan, Shi-Yuan Wang, Shang-Jen Su +1
We consider a joint communication and sensing problem over an optical link in which a low-power transmitter simultaneously communicates with a receiver and identifies the range of…

A Quantum-Memory-Free Quantum Secure Direct Communication Protocol Based on Privacy Amplification of Coded Sequences
Shang-Jen Su, Shi-Yuan Wang, Matthieu R. Bloch
We develop an information-theoretic analysis of Quantum-Memory-Free (QMF) Quantum Secure Direct Communication (QSDC) under collective attacks as an alternative to the use of a conv…

Entanglement-Assisted Bosonic MAC: Achievable Rates and Covert Communication
Yu-Chen Shen, Matthieu R. Bloch
We consider the problem of covert communication over the entanglement-assisted (EA) bosonic multiple access channel (MAC). We derive a closed-form achievable rate region for the ge…
