ReFINE: Scheduling of Distillation and Coding for Rate-Fidelity Tradeoff in Quantum Networks

Narges Alavisamani, Matthieu Bloch, Moinuddin Qureshi

In quantum networks, nodes are connected via sharing of Einstein-Podolsky-Rosen (EPR) pairs, ideally with high fidelity and high rate. However, the fidelity of EPR pairs degrades d…

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…

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…

Joint Communication and Sensing with Bipartite Entanglement over Bosonic Channels

Tuna Erdoğan, 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…

Quantum Ring States

Shang-Jen Su, Shi-Yuan Wang, Matthieu R. Bloch +2

Quantum ring states are non-Gaussian mixed states generated by uniformly modulating the phase of one arm of a bipartite Gaussian quantum resource and transmitting the modulated arm…
