One-shot dynamical resource theory
Xiao Yuan, Pei Zeng, Minbo Gao +1
A fundamental problem in resource theory is to study the manipulation of the resource. Focusing on a general dynamical resource theory of quantum channels, here we consider tasks o…
Recent advances on quantum key distribution overcoming the linear secret key capacity bound
Yingqiu Mao, Pei Zeng, Teng-Yun Chen
A crucial goal for quantum key distribution (QKD) is to transmit unconditionally secure keys over long distances. Previous studies show that the key rate of point-to-point QKD is l…
Robust shadow estimation
Senrui Chen, Wenjun Yu, Pei Zeng +1
Efficiently estimating properties of large and strongly coupled quantum systems is a central focus in many-body physics and quantum information theory. While quantum computers prom…
Phase-Matching Quantum Cryptographic Conferencing
Shuai Zhao, Pei Zeng, Wen-Fei Cao +6
Quantum cryptographic conferencing (QCC) holds promise for distributing information-theoretic secure keys among multiple users over long distance. Limited by the fragility of Green…
Single-copies estimation of entanglement negativity
You Zhou, Pei Zeng, Zhenhuan Liu
Entanglement plays a central role in quantum information processing, indicating the non-local correlation of quantum matters. However, few effective ways are known to detect the am…
