A Floquet spin chain with power-law graded Ising couplings is claimed to support time-crystalline order useful for batteries and sensing, but the scaling advantages reflect the model's growing energy scale, not a true quantum advantage.
Long-range interactions reduce STA control cost in open critical systems and enhance ergotropy in dissipative quantum battery charging via a modified protocol on a long-range Kitaev chain.
