Quadruple Bifurcated Quantum Architecture {QBQA}

This paper presents a modular quantum computingarchitecture termed the Quadruple Bifurcated Quantum Architec-ture (QBQA). The system integrates four semi-autonomous qubitdomains interconnected via photonic buses, on-chip cryogenicCMOS (cryo-CMOS) control layers, event-driven pulse routing,and adaptive quantization logic. The architecture addresseskey scalability bottlenecks in conventional monolithic systemsdeveloped by IBM and Google by reducing cryogenic routingdensity, isolating decoherence domains, and enabling distributedlogical qubit management. Speculated performance metrics arederived using coherence scaling, latency modeling, and fault-tolerance thresholds
