Semi-local observables, edge modes and quantum reference frames in quantum electromagnetism: an algebraic approach

Christopher J. Fewster, Daan W. Janssen, Kasia Rejzner

Boundaries and corners of spacetime play a vital role in understanding physical concepts including entanglement entropy, the infrared problem in QFT and quantum gravity. Standard l…

Quantum reference frames, measurement schemes and the type of local algebras in quantum field theory

Christopher J. Fewster, Daan W. Janssen, Leon Deryck Loveridge +2

We develop an operational framework, combining relativistic quantum measurement theory with quantum reference frames (QRFs), in which local measurements of a quantum field on a bac…
