Passive correction of quantum logical errors in a driven, dissipative system: a blueprint for an analog quantum code fabric

Understand

A physical realization of self correcting quantum code would be profoundly useful for constructing a quantum computer.

• In this theoretical work, we provide a partial solution to major challenges preventing self correcting quantum code from being engineered in realistic devices.
• We consider a variant of Kitaev's toric code coupled to propagating bosons, which induce a long-ranged interaction between anyonic defects.
• By coupling the primary quantum system to an engineered dissipation source through resonant energy transfer, we demonstrate a "rate barrier" which leads to a potentially enormous increase in the system's quantum state lifetime through purely passive quantum error correction, even when coupled to an infinite temperature bath.
