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…
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…
