Initialization of composite quantum systems into highly entangled states is usually a must to enable their use for quantum technologies. However, unavoidable noise in the preparation stage makes the system state mixed, hindering this goal. Here, we address this problem in the context of identical particle systems within the operational framework of spatially localized operations and classical communication (sLOCC). We define the entanglement of formation for an arbitrary state of two identical… 
Entanglement Robustness via Spatial Deformation of Identical Particle Wave Functions
It is shown that spatial indistinguishability of identical qubits can be utilized within the sLOCC operational framework to partially recover the quantum correlations spoiled by the environment.
Indistinguishable photons
Quantum mechanics allows identical particles to lose their individuality completely and become truly indistinguishable. This property of indistinguishability gives rise to exclusive quantum phenomena

Direct observation of the particle exchange phase of photons
Quantum theory stipulates that if two particles are identical in all physical aspects, the allowed states of the system are either symmetric or antisymmetric with respect to permutations of the
Directly proving the bosonic nature of photons
A simple yet effective optical set-up, employing two controllable, indistinguishable photons, is proven to allow a direct measurement of the exchange phase due to the bosonic particle statistics.

Graph Picture of Linear Quantum Networks and Entanglement
The indistinguishability of quantum particles is widely used as a resource for the generation of entanglement. Linear quantum networks (LQNs), in which identical particles linearly evolve to arrive
Lindblad Dynamics and Disentanglement in Multi-Mode Bosonic Systems
The thermal bath Lindblad master equation is considered to describe the quantum nonunitary dynamics of quantum states in a multi-mode bosonic system and it is shown that, in the regime of finite-time disentanglement, reorientation of the relaxation rate vector may significantly increase the time of disentangling.

Experimental control of remote spatial indistinguishability of photons to realize entanglement and teleportation
Remote spatial indistinguishability of identical subsystems as a direct controllable quantum resource at distant sites has not been yet experimentally proven. We design a setup capable to tune the

Entanglement of indistinguishable particles: A comparative study
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)]
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
Pattern recognition techniques for Boson Sampling validation
This work training a classifier that exploits K-means clustering to distinguish between Boson Samplers that use indistinguishable photons from those that do not, and underscores the ability to further generalize its operation beyond the scope of the examples that it was trained on.

Witnessing Genuine Multiphoton Indistinguishability.
This work describes how linear interferometers can be used to unambiguously witness genuine n-boson indistinguishability and experimentally implements this test to bound the degree of three-photon indistinguishingability in states prepared using parametric down-conversion.
A topological source of quantum light
Topologically protected edge states realized in a square array of ring resonators are used to demonstrate a robust source of heralded single photons produced by spontaneous four-wave mixing and show that they outperform their topologically trivial one-dimensional counterparts in terms of spectral robustness.
