Summary

Story summary

Researchers are making strides in quantum computing by investigating ways to create large entangled states, known as GHZ states, using current technology. They evaluated two approaches: the merging protocol, which fuses smaller states, and the growing protocol, which constructs states step by step. The merging method shines for future devices, while the growing method is ideal for today's hardware.

History

Historical Context

In 1998, IBM and Stanford University introduced the first quantum algorithm, a significant milestone in quantum computing. This innovation paved the way for IBM's 127-qubit quantum computer by 2021. As researchers continue to explore GHZ states and develop new protocols, the potential of quantum technology to transform industries like cryptography and materials science remains immense.
