- Abstract: We present techniques to construct the Deutsch-Hayden representation for
quantum field operators and apply them to an entangled state of identical
nonrelativistic spin-1/2 fermions localized in well-separated spatial regions.
Using these entangled field operators we construct operators measuring spin in
localized spatial regions, and verify that matrix elements of the
spin-measurement operators in the information-free Deutsch-Hayden state yield
the expected correlations between pairs of both entangled and unentangled
particles. The entangled Deutsch-Hayden-representation field operators furnish
an explicitly separable description of the entangled system.

A relativistic statistical field theory is constructed for a fluctuating complex-valued scalar field on a discretized Minkowski lattice.
A Hilbert space of observables is then constructed from functionals of the fluctuating complex-valued scalar field with an inner product defined in terms of expectation values of the functionals.
A bosonic Fock space is then constructed from the Hilbert space and creation and operators that act on the Fock space are defined.

Local unitary equivalence is an ingredient for quantifying and classifying entanglement.
We find a variety of local unitary invariants for arbitrary-dimensional bipartite quantum states.
We apply these invariants to estimate concurrence, a vital entanglement measure.

Embezzlement of entanglement refers to the counterintuitive possibility of extracting entangled quantum states from a reference state of an auxiliary system.
We uncover a deep connection between the operational task of embezzling entanglement and the mathematical classification of von Neumann algebras.

We find the entanglement that can be acquired by probes which interact in Gaussian spacetime regions.
We revisit the case of two gapless detectors and show that the detectors can become entangled if there is two smeared-way signalling between their interaction regions.

We investigate the relationship between projective measurements and positive operator-valued measures (POVMs) in the task of quantum steering.
We show that POVMs are equally powerful than projective measurements for the steerability of noisy singlet states.
Results help clarify the relationship between projective measurements and POVMs for the tasks of quantum steering and nonlocal information processing.

We develop a framework to characterize the separability of a specific type of one-dimensional quasiparticle known as a fermionic anyon.
We map this notion of fermionic-anyon separability to the free resources of matchgate circuits.
We also identify how entanglement between two qubits encoded in a dual-rail manner, as standard for matchgate circuits, corresponds to the notion of entanglement between fermionic anyons.

arbitrary Gaussian states [0.0]
We extend the relativistic quantum channel associated to non-perturbative models to include a very large class of Gaussian states of the quantum field.
We show that all physical results involving the non-vacuum Gaussian states can be rephrased in terms of interaction with the vacuum state.
In these non-perturbative models it is possible to perform exact computation of the R'enyi entropy.

We construct the algebra of operators acting on the Hilbert spaces of Quantum Mechanics for systems of $N$ identical particles.
We provide the explicit relation between the position and momentum operators acting in the former spaces and the field operators acting on the latter.
It may not be possible to extend the procedure to interacting field theories since it relies crucially on particle number conservation.
