Atoms Offer New Route Beyond Semiconductor Computing Limits

Dawit Hiluf Hailu of Bowie State University has developed a new computing model utilising the dynamics of two-level atoms performs classical Boolean logic as miniaturisation reaches its physical limits. The model diverges from traditional circuits by proposing a finite-state machine approach, where outputs depend on both input and the system’s initial state, encoding information within the population and coherence elements of the density matrix. Using these atomic dynamics and the potential for parallel operation, the approach offers a pathway towards scalable and potentially rapid computation despite challenges posed by environmental noise. The system provides a key method for computation and a strong basis for future development. A pathway to scalable computation…
