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…

Skew Hecke Algebras

James Waldron, Leon Deryck Loveridge

Let be a finite group, a subgroup, a commutative ring, an -algebra, and an action of on by -algebra automorphisms. We study the associated \…

Operational Quantum Reference Frame Transformations

Titouan Carette, Jan Głowacki, 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…

Quantum Reference Frames on Finite Homogeneous Spaces

Jan Głowacki, Leon Loveridge, James Waldron

We present an operationally motivated treatment of quantum reference frames in the setting that the frame is a covariant positive operator valued measure (POVM) on a finite homogen…

Incompatibility of effects in general probabilistic models

Roberto Beneduci, Leon Loveridge

We give a necessary and sufficient condition for the incompatibility of a pair of effects in a general probabilistic model in which the state space is a total convex space, which c…
