Weekly Papers on Quantum Foundations (5)

How to Build an Infinite Lottery Machine We propose two novel alternative manners of doing so, `no-leaking' (roughly that information gain causes disturbance) and `purity of cups' (roughly the existence of entangled states). Interestingly, these turn out to be equivalent in any process theory with cups and caps. Additionally, we show how the standard purification postulate can then be seen... Read more →

Branches of the Black Hole Wave Function Need Not Contain Firewalls. (arXiv:1712.04955v1 [hep-th])  hep-th updates on arXiv.org on 2017-12-16 2:35am GMT Authors: Ning Bao, Sean M. Carroll, Aidan Chatwin-Davies, Jason Pollack, Grant N. Remmen We discuss the branching structure of the quantum-gravitational wave function that describes the evaporation of a black hole. A global wave function that initially describes a classical Schwarzschild geometry is continually... Read more →

Particle or wave: there is no evidence of single photon delayed choice

Michael Devereux (Los Alamos National Laboratory) Wheeler supposed that the way in which a single photon is measured in the present could determine how it had behaved in the past. He named such retrocausation delayed choice. Over the last forty years many experimentalists have claimed to have observed single-photon delayed choice. Recently, however, researchers have proven that the quantum wavefunction of a single photon... Read more →

Light, matter, and quantum randomness generation: A relativistic quantum information perspective. (arXiv:1710.06875v1 [quant-ph])  hep-th updates on arXiv.org on 2017-10-21 12:07pm GMT Authors: Richard Lopp, Eduardo Martin-Martinez We study how quantum randomness generation based on unbiased measurements on a hydrogen-like atom can get compromised by virtue of the unavoidable coupling of the atom with the electromagnetic field. Concretely, we show that an adversary... Read more →
