The extended Wigner's friend, many- and single-worlds and reasoning from observation
Andrew Steane
The concept of an isolated system, and Frauchiger and Renner's extended `Wigner's friend' scenario are discussed. It is argued that: (i) it is questionable whether the approximatio…
Distance-critical and distance-redundant graphs
Andrew Steane
If a vertex in a graph can be deleted without affecting distances among the other vertices, we shall say it is distance-redundant. Graphs with all, some or no such vertices are dis…
Graph reconstruction and generation from one card and the degree sequence
Andrew M. Steane
Many degree sequences can only be realised in graphs that contain a `ds-completable card', defined as a vertex-deleted subgraph in which the erstwhile neighbours of the deleted ver…
Electromagnetic self-force for axially symmetric charge on a spherical shell
Andrew Steane
We obtain the fields and electromagnetic self-force of a charge distributed on the surface of a sphere undergoing rigid motion at constant proper acceleration, where the charge dis…
Matter-wave coherence limit owing to cosmic gravitational wave background
Andrew M. Steane
We study matter-wave interferometry in the presence of a stochastic background of gravitational waves. It is shown that if the background has a scale-invariant spectrum over a wide…
Fast quantum logic gates with trapped-ion qubits
V. M. Schäfer, C. J. Ballance, K. Thirumalai +4
Quantum bits based on individual trapped atomic ions constitute a promising technology for building a quantum computer, with all the elementary operations having been achieved with…
