In this paper, the Lorentz transformations of entangled Bell states with general momentum not necessarily orthogonal to the boost direction and spin are studied. We extend quantum correlations and Bell’s inequality to the relativistic regime by considering normalized relativistic observables. It is shown that quantum information along the direction perpendicular to the boost is eventually lost, and Bell’s inequality is not always violated for entangled states in special relativity. This could…

Maps Generated by Entangled Momenta: Exploring Spin Entanglement in Relativity
TLDR
The dependency between spin and momentum in relativity is conceptualized along the lines of controlled operations in quantum information theory, which leads to a systematic study of maps generated by Wigner rotations on the spin degree of freedom of the total system in different boost scenarios.
Relativistic entanglement of two particles driven by continuous product momenta
In this paper we explore the entanglement of two relativistic spin-1/2 particles with continuous momenta. The spin state is described by the Bell state and the momenta are given by Gaussian
Relativistic entanglement of two massive particles
We describe the spin and momentum degrees of freedom of a system of two massive spin--$\tfrac{1}{2}$ particles as a 4 qubit system. Then we explicitly show how the entanglement changes between
Einstein-Podolsky-Rosen correlations of vector bosons
We calculate the joint probabilities and the correlation function in Einstein-Podolsky-Rosen\char21{}type experiments with a massive vector boson in the framework of quantum field theory. We report
Transformation properties and entanglement of relativistic qubits under space-time and gauge transformations
We revisit the properties of qubits under Lorentz transformations and, by considering Lorentz invariant quantum states in the Heisenberg formulation, clarify some misleading notation that has
Relativistic Bell Test within Quantum Reference Frames.
TLDR
It is shown that Bell's inequalities for a pair of particles can be maximally violated in a special-relativistic regime, even without any postselection of the momentum of the particles, which opens up the possibility of extending entanglement-based quantum communication protocols to relativistic regimes.
Spin Fidelity for Three-Qubit Greenberger-Horne-Zeilinger and W States Under Lorentz Transformations
Constructing the reduced density matrix for a system of three massive spin-$\frac{1}{2}$ particles described by a wave packet with Gaussian momentum distribution and a spin part in the form of GHZ or
Bell’s inequality with Dirac particles
We study Bell’s inequality using the Bell states constructed from four component Dirac spinors. Spin operator is related to the Pauli-Lubanski pseudo vector which is relativistic invariant operator.
Relativistic quantum nonlocality for the three-qubit Greenberger-Horne-Zeilinger state
Lorentz transformation of the three-qubit Greenberger-Horne-Zeilinger (GHZ) state is studied. Also we obtain the relativistic spin joint measurement for the transformed state. Using these results it
Tripartite Entanglement and Lorentz Transformation
Entanglement of tripartite spin states under Lorentz transformations is studied in the context of Bell’s inequality and positive partial transpose criterion. First the relativistic analogue of Bell’s

On entanglement and Lorentz transformations
TLDR
By explicit calculation of the Wigner rotation, this work describes the relativistic analog of the Bell states as viewed from two inertial frames moving with constant velocity with respect to each other.
Quantum entanglement of moving bodies.
We study the properties of quantum entanglement in moving frames, and show that, because spin and momentum become mixed when viewed by a moving observer, the entanglement between the spins of a pair
Quantum Information and Relativity Theory
Quantum mechanics, information theory, and relativity theory are the basic foundations of theoretical physics. The acquisition of information from a quantum system is the interface of classical and

We formulate the Einstein-Podolsky-Rosen (EPR) gedankenexperiment within the framework of relativistic quantum theory to analyze a situation in which measurements are performed by moving observers.
Einstein-Podolsky-Rosen correlation seen from moving observers
TLDR
It is shown that the observers must measure the spin in appropriately chosen different directions in order to observe the perfect anti-correlation in the observers' frame.

We consider a single free spin- 1 / 2 particle. The reduced density matrix for its spin is not covariant under Lorentz transformations. The spin entropy is not a relativistic scalar and has no
