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…
