Multiple-Access Quantum Key Distribution Networks
Mohsen Razavi
This paper addresses multi-user quantum key distribution networks, in which any two users can mutually exchange a secret key without trusting any other nodes. The same network also…
Incoherent dynamics in the toric code subject to disorder
Beat Röthlisberger, James R. Wootton, Robert M. Heath +2
We numerically study the effects of two forms of quenched disorder on the anyons of the toric code. Firstly, a new class of codes based on random lattices of stabilizer operators i…
Improved Eavesdropping Detection in Quantum Key Distribution
Muhammad Mubashir Khan, Jie Xu, Almut Beige
Employing the fundamental laws of quantum physics, Quantum Key Distribution (QKD) promises the unconditionally secure distribution of cryptographic keys. However, in practical real…
Layer by layer generation of cluster states
Katherine L. Brown, Dominic Horsman, Viv Kendon +1
Cluster states can be used to perform measurement-based quantum computation. The cluster state is a useful resource, because once it has been generated only local operations and me…
Extending the validity range of quantum optical master equations
Adam Stokes, Andreas Kurcz, Tim P. Spiller +1
This paper derives master equations for an atomic two-level system for a large set of unitarily equivalent Hamiltonians without employing the rotating wave and certain Markovian ap…
Classification of Entanglement in Symmetric States
Martin Aulbach
Quantum states that are symmetric with respect to permutations of their subsystems appear in a wide range of physical settings, and they have a variety of promising applications in…
