Communication through coherent control of quantum channels
Alastair A. Abbott, Julian Wechs, Dominic Horsman +2
A completely depolarising quantum channel always outputs a fully mixed state and thus cannot transmit any information. In a recent Letter [D. Ebler et al., Phys. Rev. Lett. 120, 12…
On the definition and characterisation of multipartite causal (non)separability
Julian Wechs, Alastair A. Abbott, Cyril Branciard
The concept of causal nonseparability has been recently introduced, in opposition to that of causal separability, to qualify physical processes that locally abide by the laws of qu…
Experimentally Probing the Algorithmic Randomness and Incomputability of Quantum Randomness
Alastair A. Abbott, Cristian S. Calude, Michael J. Dinneen +1
The advantages of quantum random number generators (QRNGs) over pseudo-random number generators (PRNGs) are normally attributed to the nature of quantum measurements. This is often…
Anomalous Weak Values Without Post-Selection
Alastair A. Abbott, Ralph Silva, Julian Wechs +2
A weak measurement performed on a pre- and post-selected quantum system can result in an average value that lies outside of the observable's spectrum. This effect, usually referred…
Semi-device-independent characterisation of multipartite entangled states and measurements
Armin Tavakoli, Alastair A. Abbott, Marc-Olivier Renou +2
The semi-device-independent framework allows one to draw conclusions about properties of an unknown quantum system under weak assumptions. Here we present a semi-device-independent…
