Scientists at the University of Sydney have for the first time demonstrated improvement in quantum computers by using codes designed to detect and discard errors in the logic gates of such machines.
An international team of scientists led by the University of Groningen's Zernike Institute for Advanced Materials created quantum bits that emit photons that describe their state at wavelengths close to those used by telecom ...
Information is typically stored in physical systems, such as memory devices. But in a new study, physicists have investigated an alternative way to store and hide information, which is by storing it only in the quantum correlations ...
Scientists at the Department of Energy's Oak Ridge National Laboratory are the first to successfully simulate an atomic nucleus using a quantum computer. The results, published in Physical Review Letters, demonstrate the ...
NIST researchers have pioneered a process that drastically simplifies fabrication of the kind of nanoscale microchip features that may soon form the basis of a quantum computer, among other applications.
Physicists have designed a new method for transmitting big quantum data across long distances that requires far fewer resources than previous methods, bringing the implementation of long-distance big quantum data transmission ...
Computing power has grown exponentially over many decades, so why is the much-promised next leap of quantum computers taking so long to arrive?
Researchers have taken an important step toward the long-sought goal of a quantum computer, which in theory should be capable of vastly faster computations than conventional computers, for certain kinds of problems. The new ...
Nanomaterials have the potential to improve many next-generation technologies. They promise to speed up computer chips, increase the resolution of medical imaging devices and make electronics more energy efficient. But imbuing ...
Quantum computers hold great potential, but they remain hard to build because their basic components—individual quantum systems like atoms, electrons or photons—are fragile. A relentless and noisy background constantly ...
