Abstract

Inspired by biological molecular machines, we explore the idea of an active quantum robot the purpose of which is to delay decoherence. A conceptual model capable of partially protecting arbitrary logical qubit states against single-physical-qubit errors is presented. Implementation of an instance of that model-the entanglement qubot-is proposed using laser-dressed Rydberg atoms. The dynamics of the system are studied using stochastic wave-function methods.
