Tight synchronization between classical GPU acceleration clusters and quantum processors via ultra-low latency PCIe/CXL quantum bus interconnects.
Hybrid algorithms require thousands of iterations between quantum expectation value evaluations and classical parameter optimizations. The quantum hypervisor provides zero-copy DMA buffers between GPU memory and quantum pulse controllers, cutting end-to-end loop latency by over 80%.
When a quantum circuit exceeds the qubit count of a single QPU, the hypervisor leverages quantum circuit knitting and photonic entanglement interconnects to slice the circuit across multiple cryostats, reconstructing the joint probability density function on classical tensor network simulators.
