perspectiva aiqbenchCalcul cuantic

This research establishes the perturbative stability of self-correcting memory in 3D Wegner gauge theory using a novel "gauge averaging" technique. The findings demonstrate that fluctuation stabilization can enhance robustness against small Hamiltonian perturbations up to a finite critical temperature, offering theoretical insights into fault-tolerant quantum architectures.

Perturbatively Stable Self-Correcting Classical Memory from Gauge Averaging

arXiv:2607.20605v1 Announce Type: new Abstract: We show that the self-correcting memory in 3d Wegner gauge theory is stable to arbitrary small enough perturbations of the Hamiltonian. Our proof relies on a new method we dub ``gauge averaging'', which gives conditions under which explicitly broken gauge symmetries are effectively restored by fluctuations. These conditions show that the self-correcting memory phase is fluctuation stabilized, with its robustness to perturbations increasing with increasing temperature, up to some $T_c > 0$.
