Uncertainty Relations Relative to Phase-Space Quantum Reference Frames
Miguel Jorquera Riera, Leon Loveridge
We study Heisenberg's uncertainty relation relative to a quantum reference frame (QRF). We introduce the QRF as a covariant phase-space observable, show that when described relativ…

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…
