Ternary-tree fermion-into-qubit code

Ternary-tree fermion-into-qubit code[1]

Description

A fermion-into-qubit encoding defined on ternary trees that maps Majorana operators into Pauli strings of weight \(\lceil \log_3 (2n+1) \rceil\).

Cousin

Bravyi-Kitaev transformation (BKT) code— The ternary-tree fermion-into-qubit code improves over the BKT code by a factor of \(\approx 1.58\) in the weight of encoded fermionic operators [1].
