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…

Operational Quantum Reference Frame Transformations
Titouan Carette, Jan GÅowacki, Leon Loveridge
Quantum reference frames are needed in quantum theory for much the same reasons that reference frames are in classical theories: to manifest invariance in line with fundamental rel…
