Caltech & UCSD Propose 3D Passive Self-Correcting Quantum Memory

Researchers from Caltech and UC San Diego propose a three-dimensional passive self-correcting quantum memory that could preserve quantum information for exponentially long times at finite temperatures without active error correction (arXiv:2605.10943). A passive self-correcting memory would dramatically simplify quantum computer architectures by eliminating continuous real-time error correction overhead. The proposal is theoretical and awaits experimental validation.
