Using a matrix of nano-sized memristors, researchers
working at the Royal Melbourne Institute of Technology (RMIT) and the
University of California, Santa Barbara claim to have constructed the world’s
first electronic memory cell that effectively mimics the analog process of the
human brain. By storing memories as multiple threads of varying information,
rather than a collection of ones and zeroes, scientists believe that this
device may prove to be the first step towards creating a completely artificial,
Before the dream of quantum computing is realized, a number of inherent problems must first be solved. One of these is the ability to maintain a stable memory system that overcomes the intrinsic instability of the basic unit of information in quantum computing – the quantum bit or "qubit". To address this problem, Physicists working at the University of California Santa Barbara (UC Santa Barbara) claim to have created breakthrough circuitry that continuously self-checks for inaccuracies to consistently maintain the error-free status of the quantum memory.
This past Friday was not a good day for asteroid-human relations with asteroid 2012 DA14
passing a mere 27,700 km (17,200 miles) from the Earth just a few hours after a meteor exploded over the Russian city of Chelyabinsk, damaging hundreds of buildings and injuring thousands. Scientists have been quick to point out that both of these events – a meteor exploding over a populated area and a large asteroid passing through Earth's geosynchronous orbit – are quite rare, but when the worst case scenario is the complete annihilation of all life on Earth, it's probably best to be prepared. That's why researchers in California recently proposed DE-STAR – a system which could potentially harness the sun's energy to dissolve wayward space rocks up to ten times larger than 2012 DA14 with a vaporizing laser.
, researchers at UC Santa Barbara have created a high-performance detector that draws inspiration from the anatomy of a dog's nose to accurately identify substances – including explosives and narcotics – from very small concentrations of airborne molecules.
John Martinis’ research group at the University of California at Santa Barbara has created the first quantum computer
with the quantum equivalent of conventional Von Neumann architecture. This general-purpose programmable quantum computer is realized using superconducting circuits and offers greater potential for large-scale quantum computing than the one-problem devices that have been demonstrated in this emerging field to date.
Scientists at UC Santa Barbara
have made important advances in the field of spintronics by demonstrating the ability to electrically manipulate, at room temperatures, the quantum states of electrons trapped in the atomic structural defects of diamond crystals. Despite previous indications to the contrary, such quantum states can be manipulated very quickly, even at gigahertz frequencies, paving the way to significantly faster quantum computing
Scientists at UC Santa Barbara have developed a biological mechanism that can act as an entirely new means of drug delivery, carrying with it the potential to make treating illness even more effective. Rather than simply circulating in the bloodstream, the laboratory-developed peptide can deliver nanoparticles directly into tissue.
