K-complexity and the Jordan-Wigner transformation
… be non-trivial due to the existence of duality transformations such as the Jordan-Wigner (JW) transformation which map small operators to large, non-local operators. We investigate this claim directly in the case of the JW transformation which maps the XY Heisenberg chain to the Kitaev chain. We …

The Classical Limit of Quantum Theory
… are formulated and it is shown that the Wigner transformation can serve as a natural reduction function in a reduction which satisfies the formal and nonformal conditions. Finally, it is argued that this reduction does not aid in solving the problem of providing an adequate metaphysical …

Defining, classifying and optimising fermion–qubit mappings
… Pauli–based mappings, which include ternary tree transformations, and the product–preserving mappings, which include classical, affine, and linear encodings of the Fock basis. Deriving the explicit formula for the Majorana operators of affine encodings shows that they are the intersection of the …
