Capacity-Time Trade-off in Quantum Memory
Analysis
This paper addresses a critical challenge in quantum memory: the limitations imposed by real-world imperfections like disordered coupling and detuning. It moves beyond separate analyses of these factors to provide a comprehensive model that considers their correlated effects. The key contribution is identifying a fundamental trade-off between storage capacity, storage time, and driving time, setting a universal limit for reliable storage. The paper's relevance lies in its potential to guide the design and optimization of quantum memory devices by highlighting the interplay of various imperfections.
