Scientists Build Quantum Computer That Snaps Together Like LEGOs
A modular quantum processor design shows ~99% fidelity. It paves the way for scalable quantum computing. What do children’s building blocks and quantum computing have in common? The answer is modularity. Constructing a quantum computer as a single, unified device proves extremely difficult. Th
Unlike these restrictive monolithic designs, modular architectures offer greater scalability, easier hardware improvements, and resilience to inconsistencies, making them a more promising path for constructing quantum networks.
