Networking a qubit is in some ways similar to classical engineering, and in others vastly different. This second article in a series on quantum networking discusses the theoretical (but necessary) components of a next-generation, multi-QPU network.

Quantum systems are not mystical black boxes, but rather rigorously structured architectures with familiar analogs. This note provides a foundation for quantum computing using concepts familiar to classical engineers, x86 architects and network professionals. It maps qubits, quantum gates and qubit connectivity graphs into well-known ideas such as transistors, instruction sets and data center fabrics, making quantum systems easier to understand without diluting the physics.
