Efficient Multiparty Quantum Key Distribution over Quantum Networks
Samuel Oslovich, Bing Wang, Walter Krawec +1
Multiparty quantum key distribution (QKD) is useful for many applications that involve secure communication or collaboration among multiple parties. While it can be achieved using…
Protocols for creating and distilling multipartite GHZ states with Bell pairs
Sébastian de Bone, Runsheng Ouyang, Kenneth Goodenough +1
The distribution of high-quality Greenberger-Horne-Zeilinger (GHZ) states is at the heart of many quantum communication tasks, ranging from extending the baseline of telescopes to…
Optimising repeater schemes for the quantum internet
Kenneth Goodenough, David Elkouss, Stephanie Wehner
The rate at which quantum communication tasks can be performed using direct transmission is fundamentally hindered by the channel loss. Quantum repeaters allow, in principle, to ov…
Near-term quantum-repeater experiments with nitrogen-vacancy centers: Overcoming the limitations of direct transmission
Filip Rozpędek, Raja Yehia, Kenneth Goodenough +5
Quantum channels enable the implementation of communication tasks inaccessible to their classical counterparts. The most famous example is the distribution of secret key. However,…
Converse bounds for quantum and private communication over Holevo-Werner channels
Thomas P. W. Cope, Kenneth Goodenough, Stefano Pirandola
Werner states have a host of interesting properties, which often serve to illuminate the unusual properties of quantum information. Starting from these states, one may define a fam…
