Quantum meronomic frames [PDF]
arXiv, 2019 Composite quantum systems can be decomposed into subsystems in many different inequivalent ways. We call a particular decomposition a meronomic reference frame for the system. We apply the ideas of quantum reference frames to characterize meronomic frames, identify tasks that require such frames to accomplish, and show how asymmetric quantum states can

Realizing fully reference-frame-independent quantum key distribution by exploiting quantum discord [PDF]
arXiv, 2023 Reference-frame-independent quantum key distribution was proposed to generate a string of secret keys without a shared reference frame. Based on the Bloch sphere, however, the security analysis in previous methods is only independent on azimuthal angle, while a reference frame is determined by both polar angle and azimuthal angle. Here, we propose a 3 \

Time-reversal frameness and superselection
, 2009 We show that appropriate superpositions of motional states are a reference frame resource that enables breaking of time -reversal superselection so that two parties lacking knowledge about the other's direction of time can still communicate.

Illustrating the relativity of simultaneity [PDF]
arXiv, 2005 We present a relativistic space-time diagram that displays in true magnitudes the readings (daytimes) of two inertial reference frames clocks. One reference frame is the rest frame for one clock. This diagram shows that two events simultaneous in one reference frames are not compulsory simultaneous in the other frame. This approach has a bi-dimensional

How to Complete the Description of Physical Reality by Non-local Hidden Variables? [PDF]
arXiv, 2009 Which non-local hidden variables could complement the description of physical reality? The present model of extended Newtonian dynamics (MEND) is generalize but not alternative to Newtonian Dynamics because its extended Newtonian Dynamics to arbitrary reference frames. It Is Physics of Arbitrary Reference Frames.
arxiv
, 2001 The correlations between the outcomes of pairs of spin component measurements on particles in the singlet state exist and can be observed independently of any a priori given frame of reference.

Local criteria for the existence of an accelerated frame of reference [PDF]
arXiv, 2002 A local criteria for the existence of an accelerated frame of reference is found. An accelerated frame of reference could exist in all regions where a non-null (non-isotropic) vector field does not degenerate in a null (isotropic) vector field.

Reference frame agreement in quantum networks [PDF]
, 2013 In order to communicate information in a quantum network effectively, all network nodes should share a common reference frame. Here, we propose to study how well m nodes in a quantum network can establish a common reference frame from scratch, even though t of them may be arbitrarily faulty.

The Absolute Frame of Reference [PDF]
The manuscript found the formula to calculate the real velocity of the earth and the maximum velocity in the universe, the values of the quantities after calculation as follows: V_earth = 1.852819296∗10^8 m/s.--

An Autonomous Reference Frame for Relativistic GNSS
, 2013 Current GNSS systems rely on global reference frames which are fixed to the Earth (via the ground stations) so their precision and stability in time are limited by our knowledge of the Earth dynamics.
