Qubit construction in 6D SCFTs

We consider a class of 6D superconformal field theories (SCFTs) which have a large N limit and a semi-classical gravity dual description.Using the quiver-like structure of 6D SCFTs we study a subsector of operators protected from large operator mixing.These operators are characterized by degrees of freedom in a one-dimensional spin chain, and the associated states Heels are generically highly entangled.This provides a concrete realization of qubit-like states in a strongly coupled quantum field theory.Renormalization group flows triggered by deformations of 6D UV fixed points translate to specific deformations of these one-dimensional spin chains.

We also present a conjectural spin chain Hamiltonian which tracks the evolution of these states as a function of renormalization group flow, and study qubit manipulation 3 Pack in this setting.Similar considerations hold for theories without AdS duals, such as 6D little string theories and 4D SCFTs obtained from compactification of the partial tensor branch theory on a T2.
