A team formed by IBM Research scientist Dr. Leo Gross, University Regensburg professor Dr. Jascha Repp, and University Santiago de Compostela professor Dr. Diego Peña Gil has received a European Research Center (ERC) Synergy Grant for their project “Single Molecular Devices by Atom Manipulation” (MolDAM).
In the paper “Coherent spin manipulation of individual atoms on a surface,” published in the journal Science, our team demonstrated the use of single atoms as qubits for quantum information processing. This is the first time a single-atom qubit has been achieved using a Scanning Tunneling Microscope.
How did we get from the Palm Pilots of the 90s to the ultra-powerful smart phones of today? In large part, because of scaling, where integrated circuits are made with smaller feature sizes fitting more and more circuit elements in the same area of silicon at each technology generation. This sets our expectations that in […]
Our team at IBM Research developed a new technique to control the magnetism of a single copper atom, a technology that could one day allow individual atomic nuclei to store and process information. In a paper published today in the journal Nature Nanotechnology, our team demonstrated that we can control the magnetism of a single […]
Nanomaterials offer unique optical and electrical properties and bottom-up integration within industrial semiconductor manufacturing processes. However, they also present one of the most challenging research problems. In essence, semiconductor manufacturing today lacks methods for depositing nanomaterials at predefined chip locations without chemical contamination. We think that graphene, one of the thinnest, strongest, most flexible and most […]
Carbon nanotubes (CNT) appeal to the semiconductor industry because they’re superior electrical conductors compared to silicon with a mere 1 nanometer body thickness. So why don’t we have CNT chips in everything from mainframes to mobile devices, yet? Scalability of the transistor and large-scale integration are still big challenges. But two papers my colleagues and […]
Last year the world consumed almost 97 million barrels of oil per day. What if I told you that many more barrels still remain in those same wells? Deep inside the rock, 60 percent and more of a reservoir’s oil remains trapped in capillaries which are sometimes only tens to hundreds of nanometers wide (For […]
Published today in the peer-reviewed journal Nano Letters, IBM scientists have shot an electron through an III-V semiconductor nanowire integrated on silicon for the first time. This achievement will form the basis for sophisticated quantum wire devices for future integrated circuits used in advanced powerful computational systems. IBM scientist and lead author on the paper Dr. Johannes […]
When we announced the industry’s first functional 7 nanometer node (7nm) test chips in 2015, with our GLOBALFOUNDRIES and Samsung partners, we knew the process for the chips to reach “manufacturing maturity” – perhaps as early as next year, would be rapid. As that effort accelerates in the semiconductor industry, IBM continues to push the […]
Published today, using a technique which looks like trampoline, IBM scientists have measured the thermal conductance of metallic quantum point contacts made of gold down to the single-atom level at room temperature for the first time. As everything scales to the nanoscale, heat – more precisely, the loss of it – becomes an issue in […]
IBM 5 in 5: Medical labs “on a chip” will serve as health detectives for tracing disease at the nanoscale
The earlier a disease is diagnosed, the more likely it is to be cured or successfully managed. For example, breast cancer and prostate cancer detected and treated at stage one have five-year survival rates of nearly 100 percent. At stage four, this rate drops to around 26 percent for breast cancer and 28 percent for […]
Earlier this year, scientists at ETH Zurich and IBM Research – Zurich published a new method in Science Advances to fabricate artificial molecules out of different types of microspheres, small round particles with a diameter of 1 micrometer – roughly the size of bacteria. While tiny, the scientists believe that one day these microscopic objects […]
