  author={A. C. C. Lourencco and Tiago Debarba and Eduardo Inacio Duzzioni},

There is a debate in course about the quantification of entanglement of indistinguishable particles and recently a new method due to Lo Franco and Compagno (LFC) [Sci. Rep. \textbf{6}, 20603 (2016)] appeared with the aim of settling the controversies of this debate. In this work we show that the LFC approach can be recovered using the second quantization formalism and a local single-particle basis to perform the trace over one particle state. The use of the second quantization formalism has the…

Entanglement in indistinguishable particle systems

Entangling bosons through particle indistinguishability and spatial overlap.

Theoretical and experimentally investigate the behavior of entanglement between two bosons as spatial overlap and indistinguishability simultaneously vary and show that the amount ofEntanglement is a monotonically increasing function of both quantities.

Entanglement of identical particles and coherence in the first quantization language

We suggest a formalism to illustrate the entanglement of identical particles in the first quantization language (1QL). Our 1QL formalism enables one to exploit all the well-established quantum

Reduced density matrix of nonlocal identical particles

The theoretical connection among three different approaches to analyze the entanglement of identical particles is probed, showing that the symmetrized partial trace corresponds to the interior product in symmetric and exterior algebra (SEA), which also corresponding to the subalgebra restriction in the algebraic approach based on GNS representation.

Robust entanglement preparation against noise by controlling spatial indistinguishability

It is found that spatial indistinguishability, even partial, can be a property shielding nonlocal entanglement from preparation noise, independently of the exact shape of spatial wave functions.

Reduced Density Matrix of Identical Particles from Three Aspects: the First Quantization, Exterior Products, and GNS representation

By expressing the state of identical particles as exterior and elementary symmetric state vectors, the first quantization language (1QL) can be expressed, it is proved that GHJW theorem holds for identical particles.

Indistinguishability-enabled coherence for quantum metrology

Quantum coherence plays a fundamental and operational role in different areas of physics. A resource theory has been developed to characterize the coherence of distinguishable particles systems. Here

Quantum teleportation is considered a basic primitive in many quantum information processing tasks and has been experimentally confirmed in various photonic and matter-based setups. Here, we consider

Generation and evaluation of multipartite entanglement with multi-rail encoding in linear optics networks

A linear optics network (LON) is a multimode interferometer system, where indistinguishable photon inputs can create nonclassical interference that can not be simulated with classical computers. Such

Activation of indistinguishability-based quantum coherence for enhanced metrological applications with particle statistics imprint

Significance Quantum coherence has a fundamentally different origin for nonidentical and identical particles since for the latter a unique contribution exists due to indistinguishability. Here we



Dealing with indistinguishable particles and their entanglement

Here, we discuss a particle-based approach to deal with systems of many identical quantum objects (particles) that never employs labels to mark them. We show that it avoids both methodological

General criterion for the entanglement of two indistinguishable particles (10 pages)

We relate the notion of entanglement for quantum systems composed of two identical constituents to the impossibility of attributing a complete set of properties to both particles. This implies

Universality of Schmidt decomposition and particle identity

This work proves a universal Schmidt decomposition which allows faithful quantification of the physical entanglement due to the identity of particles, and finds that it is affected by single-particle measurement localization and state overlap.

Quantum entanglement of identical particles by standard information-theoretic notions

This work introduces a state-based method which, as second quantization, does not label identical particles and establishes the quantitative role played by arbitrary wave function overlaps, local measurements and particle nature in assessing entanglement by notions commonly used in quantum information theory for distinguishable particles, like partial trace.

Remarks on Entanglement and Identical Particles

It is argued that in the case of identical particles the most natural identification of separability is via the factorization of mean values of commuting observables, and it thus follows that separability and entanglement depend both on the state and on the choice of observables and are not absolute notions.
