A group of physicists at UNSW Sydney have built a super-fast version of the central building block of a quantum computer. The research is the milestone result of a vision first outlined by scientists 20 years ago.
Purdue University researchers are among the first to build what could be a quantum version of a transistor -- with qudits.
Rutgers researchers have created a device that can determine whether targeted chemotherapy drugs are working on individual cancer patients. The portable device, which uses artificial intelligence and biosensors, is up to 95.9% accurate in counting live cancer cells when they pass through electrodes, according to a study in the journal Microsystems & Nanoengineering.
A new University at Buffalo-led study describes how researchers wirelessly controlled FGFR1 -- a gene that plays a key role in how humans grow from embryos to adults -- in lab-grown brain tissue. The ability to manipulate the gene, the study's authors say, could lead to new cancer treatments, and ways to prevent and treat mental disorders such as schizophrenia.
Two physics research groups at the University of Kansas have generated free electrons from organic semiconductors when combined with a single atomic layer of molybdenum disulfide, a recently discovered two-dimensional semiconductor.
A Japanese research team led by Osaka University produced Fe3O4 nanowires on 10-nm length scales by deposition on an MgO substrate. When cooled to 110 K, the nanowires showed a sharp Verwey transition -- greater resistivity resulting from a change in crystal structure. This switching is essential for nanoelectronics, but hard to achieve in Fe3O4 nanowires. It was possible because of the low density of antiphase boundary defects, and will promote advances in green electronic technologies.
Physicists have theorized that a new type of material, called a three-dimensional (3D) topological insulator (TI), could be a candidate to create qubits for quantum computing due to its special properties. A study found that when the TI's insulating layers are as thin as 16 quintuple atomic layers across, the top and bottom metallic surfaces begin to destroy their metallic properties.
Researchers from the National University of Singapore have incorporated metamaterials into conventional clothing to dramatically improve signal strength between wearable electronic devices. This innovation could have future applications in high-tech athletic wear and medical apparel.
An end-to-end transmitter-receiver created by engineers in UCI's Nanoscale Communication Integrated Circuits Labs, is a 4.4-millimeter-square silicon chip that is capable of processing digital signals with significantly greater speed and energy efficiency because of its unique digital-analog architecture.
There's no known way to prove a three-dimensional 'quantum spin liquid' exists, so Rice University physicists and their collaborators did the next best thing: They showed their crystals of cerium zirconium pyrochlore had the right stuff to qualify as the first possible 3D version of the long-sought state of matter.
