Researchers at Oak Ridge National Laboratory have developed a groundbreaking technology that allows them to precisely manipulate individual atoms, opening the door to unprecedented advancements in quantum computing, communication, and beyond.
Unlocking the Quantum Realm
This research paper discusses how the research team has developed essentially a new kind of microscope called a ‘synthescope’, which allows them to write with atoms and precisely place them where they are needed for new, smarter materials. Atomic-scale precision is necessary to leverage the exotic quantum effects — including entanglement — that will enable entirely new classes of computers, communication technologies, and sensors.
At the atomic level, a direct control over materials can be achieved by the scientist due to their ability to manipulate the building blocks of materials, and unique structures and compositions that otherwise could not have been produced through normal ways are attained. This level of consistency will enable a range of new experimental processes, including in the field of quantum information science, microelectronics and catalysis as well general progress in the basic science of materials synthesis.
Changing the Fabrication Paradigm
The particular catch about the feat achieved by the research team—it employs a scanning transmission electron microscope (STEM) as an atomic-scale material manipulation platform. Using the electron beam to create graphene defects, the team can then fill these defects with high precision with atoms of another element, such as tin.
This process of ‘direct writing’ at the atomic scale was a remarkable achievement and allowed the researchers to position individual atoms continually and precisely where they were needed. This technology boasts unprecedented precision compared to existing fabrication methods, and allows for new-to-nature materials with desired electronic, optical, chemical, or structural behaviour.
The researchers anticipate that this technology will transform the way in which materials and devices are created at the atomic scale, one atom at a time. All this, combined with automated beam control and AI-based analysis, is expected to bring in the era of synthescope — a different atomic-scale fabrication; precise;confusing surprized custom.
Conclusion
The cutting-edge discoveries of the Oak Ridge National Laboratory research team could change the face of how we fabricate materials in applications ranging from quantum computing and communication to microelectronics and catalysis. This technology enables scientists to control single atoms with enhanced precision, marking the tipping point into groundbreaking new capabilities in quantum and beyond — ushering a future where what was previously unthinkable is an everyday reality.
