New technology paves the way for improved information transfer in both classical and quantum regimes. Many of us swing through gates every day — points of entry and exit to a space like a garden, park or subway. Electronics have gates too. These control the flow of information from one place to anot...

Georgia Tech Research Institute (GTRI) researchers have developed a more efficient method for creating entangled qubits by moving trapped ions through a stationary laser beam, potentially simplifying quantum computing systems. Trapped ions excited with a laser beam can be used to create entangl...

A collaborative new study led by researchers at the University of Pennsylvania demonstrates topological control capabilities in an acoustic system, with implications for applications such as 5G communications and quantum information processing. New research published in Nature Electronics describes ...

New Optical System Designed To Target and Control Individual Atoms Researchers have pioneered a groundbreaking technique utilizing laser light to control individual qubits made of barium more robustly than any other method currently known. Reliably controlling qubits is a critical step towards actua...

From the press release at https://www.nist.gov/news-events/news/2017/08/nist-crafts-next-generation-safeguards-information-systems-and-internet - "The National Institute of Standards and Technology (NIST) has issued a new draft revision of its widely used Special Publication (SP) 800-53, Security an...

Abstract: "The growing movement to connect literally everything to the internet (internet of things or IoT) through ultra-low-power embedded microprocessors poses a critical challenge for information security. Gate-level tracking of information flows has been proposed to guarantee information flow s...

University of Vermont and MITRE studies show that near-light-speed differences in stock prices may be exploited by traders with faster information systems. Imagine standing in the grocery store, looking at a pile of bananas. On your side of the pile, the manager has posted yesterday’s newspape...

Berkeley Lab scientists tap into graphene’s hidden talent as an electrically tunable superconductor, insulator, and magnetic device for the advancement of quantum information science. Ever since graphene’s discovery in 2004, scientists have looked for ways to put this talented, atomicall...

Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have for the first time created and imaged a novel pair of quantum dots — tiny islands of confined electric charge that act like interacting artificial atoms. Such “coupled” quantum dots could serve as a ro...

Quantum communication—where information is sent through particles, typically entangled photons—has the potential to become the ultimate secure communication channel. Not only is it nearly impossible to eavesdrop on quantum communication, those who try will also leave evidence of their indiscretions....

Our brains have an upper limit on how much they can process at once due to a constant but limited energy supply, according to a new UCL study using a brain imaging method that measures cellular metabolism. The study, published in the Journal of Neuroscience, found that paying attention can change ho...

Berkeley Lab-led center to catalyze U.S. leadership in quantum information science, and strengthen the nation’s research community to accelerate commercialization. The Department of Energy (DOE) has awarded $115 million over five years to the Quantum Systems Accelerator (QSA), a new research center ...

Physicists use antiferromagnetic rust to carry information over long distances at room temperature. Be it with smartphones, laptops, or mainframes: The transmission, processing, and storage of information is currently based on a single class of material – as it was in the early days of computer scie...

Scientists Tame Photon-Magnon Interaction Working with theorists in the University of Chicago’s Pritzker School of Molecular Engineering, researchers in the U.S. Department of Energy’s (DOE) Argonne National Laboratory have achieved a scientific control that is a first of its kind. They demonstrated...

Scientists found that the chaotic behavior of energized qubits scales linearly, not exponentially—offering a new way to simulate large quantum systems using far fewer resources. Physicists have discovered a potentially game-changing feature of quantum bit behavior that would allow scientists to simu...

Researchers have found a way to use light and a single electron to communicate with a cloud of quantum bits and sense their behavior, making it possible to detect a single quantum bit in a dense cloud. The researchers, from the University of Cambridge, were able to inject a ‘needle’ of h...

Protocol to reverse engineer Hamiltonian models advances automation of quantum devices. Scientists from the University of Bristol’s Quantum Engineering Technology Labs (QETLabs) have developed an algorithm that provides valuable insights into the physics underlying quantum systems — paving the...

A team of scientists has uncovered a system in the brain used in the processing of information and in the storing of memories — akin to how railroad switches control a train’s destination. The findings offer new insights into how the brain functions. “Researchers have sought to identify neural circu...

A Department of Energy-funded project between Argonne and the University of Illinois Urbana-Champaign explores coupling magnetism and microwaves for quantum discoveries. The U.S. Department of Energy (DOE) has recently funded both DOE’s Argonne National Laboratory and the University of Illinois Cham...
