The convergence of quantum cryptography with applications used in everyday life is a topic
drawing attention from the industrial and academic worlds. The development of quantum …

The increasingly pervasive connectivity of today's information systems brings up new
challenges to security. Traditional security has accomplished a long way toward protecting …

Quantum key distribution (QKD) relies on the laws of physics to establish a symmetric binary
key between remote parties. A QKD link involves the realization of a quantum channel for …

Quantum key distribution (QKD) promises information theoretic security. However, the
distances over which complete security can be achieved are fundamentally limited in the …

Besides true quantum repeaters, a trusted node paradigm seems to be inevitable for
practical implementations (at least in the short term), and one should consider configurations …

We investigate infeasibility issues arising along network design for information-theoretically
secure cryptography. In particular, we consider the problem of communication in perfect …

We provide various results about the transmission capacity of quantum networks. Our
primary focus is on algorithmic methods to efficiently compute upper-bounds to the traffic that …

Because quantum key distribution is a technology for establishing keys for symmetric
encryption (preferably one-time pads, but more practically keys for AES or other …

利用纠缠渗流的方法, 在量子随机网络中任意两个节点间建立远距离纠缠态,
同时还进行了局部纠缠交换的操作. 通过此操作改变了网络中局部节点间的连接情况 …

Quantum key distribution is renowned for information-theoretic security on point-to-point
connections, while it is by itself not directly capable of end-to-end security. Multipath …
