Modular quantum computing

Definition

Modular quantum computing is an approach that emphasizes the construction of quantum computers in a modular fashion, allowing different components or subsystems to be developed and operated independently before being integrated into a larger quantum system. This method facilitates scalability and easier troubleshooting, as components can be upgraded or replaced without affecting the entire system. Modular quantum computing is particularly relevant when addressing challenges related to scaling quantum systems, where maintaining coherence and operational efficiency becomes increasingly complex as the number of qubits rises.
