Query: Entanglement in Algebraic Quantum Mechanics: Majorana fermion systems   Many-body entanglement is studied within the algebraic approach to quantum
physics in systems made of Majorana fermions. In this framework, the notion of
separability stems from partitions of the algebra of observables and properties
of the associated correlation functions, rather than on particle tensor
products. This allows obtaining a complete characterization of non-separable
Majorana fermion states. These results may find direct applications in quantum
metrology: using Majorana systems, sub-shot noise accuracy in parameter
estimations can be achieved without preliminary, resource consuming, state
entanglement operations.
