What Represents Space-time? And What Follows for Substantivalism \emph{vs.} Relationalism and Gravitational Energy?. (arXiv:2208.05946v1 [physics.hist-ph]) 上午9:40 | physics.hist-ph updates on arXiv.org Authors: J. Brian Pitts The questions of what represents space-time in GR, the status of gravitational energy, the substantivalist-relationalist issue, and the (non)exceptional status of gravity are interrelated. If space-time has energy-momentum, then space-time is substantival. Two extant ways to… Read more →

Characterizing quantum instruments: from non-demolition measurements to quantum error correction.

Due to the… Read more →

Self-testing of physical theories, or, is quantum theory optimal with respect to some information-processing task?. (arXiv:2003.00349v3 [quant-ph] UPDATED) 上午9:18 | Mirjam Weilenmann, Roger Colbeck | quant-ph updates on arXiv.org Self-testing usually refers to the task of taking a given set of observed correlations that are assumed to arise via a process that is accurately described by quantum theory, and trying… Read more →

Approaches to causality and multi-agent paradoxes in non-classical theories. (arXiv:2102.02393v1 [quant-ph]) 上午10:10 | V. Vilasini | quant-ph updates on arXiv.org This thesis reports progress in the analysis of causality and multi-agent logical paradoxes in quantum and post-quantum theories. These research areas are highly relevant for the foundations of physics as well as the development of quantum technologies. In the first… Read more →
