- We present a modular atom-array quantum computing architecture with space-time hybrid multiplexing (MAQCY), a dynamic optical tweezer-based protocol for fully connected and scalable universal quantum computation. By extending the concept of globally controlled static dual-species Rydberg atom wires [1], we develop an entirely new approach using Q-Pairs, which consist of globally controlled and temporally multiplexed dual-species Rydberg blockaded atom and superatom pairs. Space-time hybrid multiplexing of Q-Pairs achieves O(N) linear scaling in the number of required physical qubits, while preserving coherence and mitigating circuit-depth limitations through in-situ atom replacement. To demonstrate MAQCY's versatility, we implement a three-qubit quantum Fourier transform using only global operations and atom transport. We also propose a concrete implementation using ytterbium isotopes, paving the way toward large-scale, fault-tolerant quantum computing.
