Degradation of a quantum reference frame

open access: yes, 2006
We investigate the degradation of reference frames, treated as dynamical quantum systems, and quantify their longevity as a resource for performing tasks in quantum information processing. We adopt an operational measure of a reference frame's longevity,

Physics within a quantum reference frame

open access: yes, 2011
We investigate the physics of quantum reference frames. Specifically, we study several simple scenarios involving a small number of quantum particles, whereby we promote one of these particles to the role of a quantum observer and ask what is the ...

The reference-frame independence of quantum probabilities [PDF]

open access: yesarXiv, 2022
We investigate the transformation rule of a single particle wave-function under a change of reference frame. A postulate is raised, and some fundamental aspects regarding the reference-frame independence of quantum probabilities are explored.

Frame of Reference Interaction. [PDF]

open access: yes, 2002
We present a unified set of 3D interaction techniques that demonstrates an alternative way of thinking about the navigation of large virtual spaces in non-immersive environments.

Experimental Quantum Communication without a Shared Reference Frame [PDF]

open access: yes, 2006
We present an experimental realization of a robust quantum communication scheme [Phys. Rev. Lett. 93, 220501 (2004)] using pairs of photons entangled in polarization and time.

Should there be a spin-rotation coupling for a Dirac particle? [PDF]

open access: yes, 2013
It was argued by Mashhoon that a spin-rotation coupling term should add to the Hamiltonian operator in a rotating frame, as compared with the one in an inertial frame.

Quantum teleportation with infinite reference frame uncertainty and without prior alignment [PDF]

open access: yesPhys. Rev. A 100, 062306 (2019), 2018
We present two new schemes for quantum teleportation between parties whose local reference frames are misaligned by the action of a compact Lie group G. These schemes require no prior alignment of reference frames and are unaffected by arbitrary changes in reference frame alignment during execution, suiting them to situations of rapid reference frame ...

Sampled Reference Frame Algorithm Based on Space Vector Pulse Width Modulation for Five Level Cascaded H-Bridge Inverter [PDF]

open access: yes, 2014
In This paper the Sampled Reference Frame Algorithm for Five Level Cascaded H-Bridge Inverter is presented. This simple method is less computation method than Sector Identification.

Dynamics of a quantum reference frame undergoing selective measurements and coherent interactions [PDF]

open access: yes, 2010
We consider the dynamics of a quantum directional reference frame undergoing repeated interactions. We first describe how a precise sequence of measurement outcomes affects the reference frame, looking at both the case that the measurement record is ...

A computational model of the referential semantics of projective prepositions [PDF]

open access: yes, 2006
In this paper we present a framework for interpreting locative expressions containing the prepositions in front of and behind. These prepositions have different semantics in the viewer-centred and intrinsic frames of reference (Vandeloise, 1991).
