Summary: 2 independent superconducting quantum processors linked using 4 specialized superconducting microwave cables create modular multi-chip architecture. Establishing reliable inter-chip quantum state transfer channels overcomes the physical scale limitations of monolithic quantum chips. This modular interconnect strategy provides hardware developers with a practical blueprint to construct fault-tolerant, large-scale distributed quantum computers without requiring single massive dies.
