Noise Resilience of Spin Quantum Battery in the presence of DM Interactions

Abstract

Quantum batteries utilize quantum effects to enhance energy storage and work extraction, offering promising avenues for nanoscale energy applications. However, environmental noise poses a significant challenge by degrading stored energy. For a single qubit, we show that amplitude damping and bit-flip noises lead to ergotropy loss, while phase-flip noise permits partial preservation of work. Extending to a two-qubit Heisenberg XYZ model with Dzyaloshinsky-Moria interaction (DMI), we identify a critical interaction strength that enhances energy retention. We show that strong DMI and initial coherence protects ergotropy even under repeated noise applications, highlighting chiral spin interactions as a resource for noise-resilient quantum batteries.
