An international team of scientists has achieved a remarkable breakthrough in the realm of quantum computing. For the first time, they've successfully created a 'quantum entangled state' using the spins of two atomic nuclei. This breakthrough has paved the way for 'remote communication' between these nuclei. This significant accomplishment underscores the immense potential of leveraging existing semiconductor technology and manufacturing processes to develop future quantum chips. It represents a pivotal stride toward constructing large-scale quantum computers.

The research zeroed in on a technical approach that was previously deemed challenging to scale up. This method entails encoding quantum information through the spins of phosphorus atomic nuclei implanted in silicon chips. Although a team from the University of New South Wales in Australia had previously shown that quantum information could be stored for extended periods in atomic nuclei with minimal operational errors, the issue of scalability persisted as a major hurdle.

This time around, the research team managed to establish remote communication between atomic nuclei. They did this by coupling the nuclei with electrons and harnessing the interactions between these electrons. In the experimental setup, the two atomic nuclei were positioned roughly 20 nanometers apart, a distance that aligns with the standards of modern silicon technology. This milestone effectively removes the most significant barrier to scaling up silicon quantum computers that rely on atomic nucleus spins.

The newly developed method is not only robust but also scalable. It opens up the possibility of incorporating more electrons in the future, further enhancing the capabilities of quantum computing systems.
