Tight Reference Frame–Independent Quantum Teleportation [PDF]

Electronic Proceedings in Theoretical Computer Science, 2017
We give a tight scheme for teleporting a quantum state between two parties whose reference frames are misaligned by an action of a finite symmetry group.

ETRS89/D96-17 – Rezultat GNSS-izmere EUREF Slovenija 2016 ( = ETRS89/D96-17 – A result of the EUREF Slovenia 2016 GNSS campaign) [PDF]

Geodetski Vestnik, 2020
The horizontal component of the national spatial reference system of Slovenia is based on EUREF GPS campaigns at the passive GNSS-network of EUREF sites in the years 1994–1996.

GOM20: A Stable Geodetic Reference Frame for Subsidence, Faulting, and Sea-Level Rise Studies along the Coast of the Gulf of Mexico

Remote Sensing, 2020
We have established a stable regional geodetic reference frame using long-history (13.5 years on average) observations from 55 continuously operated Global Navigation Satellite System (GNSS) stations adjacent to the Gulf of Mexico (GOM).

Reduced Reference Frame Transformation Assessment in Unbalanced Three-Phase Four-Wire Systems

IEEE Access, 2023
Three-phase four-wire systems require a reference frame similar to that used in 3-phase 3-wire system configurations that allow them to be easily analysed, modelled and controlled.

Dynamics of a Quantum Reference Frame [PDF]

, 2007
We analyze a quantum mechanical gyroscope which is modeled as a large spin and used as a reference against which to measure the angular momenta of spin-1/2 particles.

Adaptive training‐feedback scheme for FDD in massive MIMO systems

IET Communications, 2023
Accurate acquisition of channel state information (CSI) is crucial but difficult in frequency division duplex (FDD) massive multiple‐input multiple‐output (MIMO) systems.

Microarcsecond instability of the celestial reference frame [PDF]

, 1998
The fluctuation of the angular positions of reference extragalactic radio and optical sources under the influence of the irregular gravitational field of visible Galactic stars is considered.

Operational Quantum Reference Frame Transformations [PDF]

Quantum
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 relativity principles and to provide a basis for the definition of observable

Concept of spatial coordinate systems, their defining and implementation as a precondition in geospatial applications [PDF]

Glasnik Srpskog Geografskog Društva, 2015
There are many users of spatial information, and quite large interest about the nature and genesis of such information. Different users found spatial information in the form of maps, plans or alphanumerical tables. Recently, there are more often

Deformed symmetries from quantum relational observables [PDF]

, 2007
Deformed Special Relativity (DSR) is a candidate phenomenological theory to describe the Quantum Gravitational (QG) semi-classical regime. A possible interpretation of DSR can be derived from the notion of deformed reference frame.
