In the paper “Integrated gallium phosphide nonlinear photonics”, recently published in the peer-reviewed journal Nature Photonics, we report on the development of high-performance photonic devices made of the crystalline semiconductor gallium phosphide. This work represents a breakthrough in the manipulation of light with semiconductor materials integrated on a chip. It opens the door to a […]
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.
IBM researchers, along with collaborators at the Universidade de Santiago de Compostela and ExxonMobil, reported in the peer-review journal Science that they have been able to resolve with unprecedented resolution the structural changes of individual molecules upon charging.
Modern digital computers have changed our lives in a variety of ways, but the technology on which they are built has still some room for improvement. As computational workloads continue to grow due to massive amounts of data and techniques like artificial intelligence, more powerful computing technologies become of paramount importance. Two of the main […]
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 […]
Our team at IBM Research − Almaden in Silicon Valley has detected the magnetism of a single atom’s nucleus, a feat that opens the door to using the nucleus as a way to sense and control magnetism at the atomic scale. This breakthrough, recently published in the journal Science, was achieved by measuring the magnetic […]
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 […]
Dissolved Ocean Carbon (DOC) in the ocean is one of the largest pools of reduced carbon on Earth. It’s about 200 times larger than the living biosphere and comparable in size to the atmospheric CO2 reservoir. Due to its complexity, less than 10 percent of dissolved organic carbon has been characterized. It’s important to understand […]
Our understanding of single-molecule electronics has become clearer and the answer involved using a common household item – salt. Building off of a previous paper in 2009, where IBM scientists and collaborators demonstrated the ability to measure the charge state of individual atoms using noncontact atomic force microscopy (AFM), they have now taken it a […]
Today, our IBM Research team published the first real world demonstration of a rocking Brownian motor for nanoparticles in the peer-review journal Science. The motors propel nanoscale particles along predefined racetracks to enable researchers to separate nanoparticle populations with unprecedented precision. The reported findings show great potential for lab-on-a-chip applications in material science, environmental sciences […]
Over the past decades, the aggressive scaling of transistors made on rigid silicon wafers has steadily boosted the performance of personal electronics and supercomputers. For emerging applications like real-time analytics and Internet of Things (IoT), high-performance logic circuits and sensors made on flexible or unconventional substrates are needed in order to enable the true computation […]
