**Summary:**
The article discusses a breakthrough in quantum computing, specifically regarding quantum entanglement. Researchers have demonstrated quantum entanglement between two atomic nuclei separated by 20 nanometers using a method that uses electrons as “telephones” to communicate between the nuclei. This is significant because it allows for scaling up quantum computers using nuclear spins, which are well-shielded from noise, while integrating with existing silicon chip technology. This advancement addresses the challenge of balancing the need for shielding quantum computing elements with the need for interaction to perform computations. The team showed the method can scale up beyond pairs of nuclei that are attached to the same electron, which opens the door to integrating nuclear spin qubits into the existing architecture of standard silicon chips.

**Quantum Leap: Scientists Achieve Entanglement Milestone, Paving Way for Scalable Quantum Computers**
**SYDNEY, AUSTRALIA – SEPTEMBER 24, 2025** – In a groundbreaking development that could revolutionize the future of computing, researchers at UNSW Sydney have announced a major advance in quantum entanglement. Published today in the journal *Science*, the team’s work demonstrates quantum entanglement between two atomic nuclei separated by a mere 20 nanometers, a feat that overcomes a key obstacle in building practical and scalable quantum computers.
Quantum entanglement, once famously dismissed by Albert Einstein as “spooky action at a distance,” is the core of how quantum computers will surpass traditional computing capabilities. The breakthrough involves using electrons as a communication channel, essentially giving the nuclei “telephones” to interact with each other, even when separated by a short distance.
“The challenge has always been balancing the need to shield the fragile computing elements from external interference with the need to interact with them for meaningful computations,” explained Professor Andrea Morello, head of the research team. “Our approach addresses this by leveraging the stability of nuclear spins, which are very well shielded from noise, and integrating them into the existing architecture of standard silicon chips.”
Until now, manipulating multiple atomic nuclei for quantum computing required them to be located very close together. This limited scalability. The new method allows for greater separation while maintaining quantum entanglement, opening the door to building larger, more powerful quantum computers.
“This is the scale at which everyday silicon transistors are fabricated,” said Morello. “Creating quantum entanglement on the 20-nanometer scale means we can integrate our long-lived, well-shielded nuclear spin qubits into the existing architecture of standard silicon chips like the ones in our phones and computers.”
The implications of this discovery are vast. Quantum computers promise to revolutionize fields such as medicine, materials science, and artificial intelligence by enabling simulations and calculations far beyond the reach of classical computers. The team is optimistic that further advancements in electron manipulation will allow for even greater entanglement distances, bringing the dream of practical, scalable quantum computers closer to reality.
