Researchers at NIST and the University of Maryland have made progress in understanding the relationship between quantum entanglement and quantum complexity. They investigated a “regular graph state” – a configuration of particles and their connections – and found that too many connections made the state useless for quantum computing.
Entanglement, a unique quantum phenomenon that links the fate of subatomic particles, is crucial for quantum computing’s power. However, the exact relationship between entanglement and quantum complexity – the number of steps needed to solve a problem – has remained unclear. The researchers found that a certain level of entanglement is necessary to fully exploit quantum complexity, but more entanglement doesn’t necessarily improve performance.
This partial answer could help optimize quantum computing systems and better understand the limits of quantum computing.
