A Statistical Framework for Dynamically Adaptive Logical Qubit Architectures for Scalable Fault-Tolerant Quantum Computing

The theoretical impediments of quantum computing to the large-scale implementation are inherently noise, decoherence, and inefficiency of the current fault-tolerant schemes. Although quantum hardware and error detection methods have made great advancements, existing methods largely use fixed logic qubit simulations and fixed noise models, which are inefficient at responding to dynamically changing noise models and do not scale. To curb this shortcoming, there is a need to have a framework that incorporates flexibility, statistical intelligence, and system optimization. In this paper, a dynamically adaptive logic qubit architecture is proposed based on a statistical model that can be used to achieve fault-tolerant quantum computing on a scale. The framework makes use of probabilistic noise modeling, real-time feedback-based reconfiguration in the continuous optimization of logical qubit structures and error correction schemes. The proposed architecture reduces the error propagation and reduces resource overhead by adding statistical inference using adaptive control mechanisms. Large-scale simulation experiments show that the given approach can suppress logical errors up to 28 percent better and reduce qubit overhead by 35 percent in comparison to the traditional fault-tolerant models that are based on static models and fault-tolerance in different noise levels. Moreover, the framework has a stable performance when the size of the system is growing, which indicates its stability and scalability. These results put dynamically adaptive logical qubit architectures as a potentially fruitful direction towards real-world and scalable quantum computing, and can be used in optimization, secure communication, and modeling of complex systems.
