Tuning electric field strength or direction restores near-perfect state transfer in hole-spin qubits via discrete spin-orbit phase-matching conditions independent of rotation axis.
Side coupling of free spins to Ising models on lattices fragments the Hilbert space into exponentially many decoupled sectors at resonance between transverse field and coupling, inducing quantum scars.
A protocol using emergent Hamiltonians enables storage of Bell-product and GHZ entangled states by making them exact eigenstates of a local Hamiltonian.
