Solving the Casimir Puzzle
Paradox of Quantum Forces in Nanodevices “Casimir Puzzle” Explained by Scientists Read More… + The operation of microdevices used in modern technology is influenced by the Casimir force caused by electromagnetic fluctuations. This is the force of attraction acting between two surfaces in the vacuum. Such an interaction between electrically neutral bodies located at a […]
Mission: Bring Qubits to Heel Via Erbium
A new spin on atoms gives scientists a closer look at quantum weirdness Artist’s rendering by Rachel Davidowitz When atoms get extremely close, they develop intriguing interactions that could be harnessed to create new generations of computing and other technologies. These interactions in the realm of quantum physics have proven difficult to study experimentally due […]
NIST Publishes Two Digital Signature Schemes: Good Enough for ICS or SCADA Security?
Recommendation for Stateful Hash-Based Signature Schemes: NIST SP 800-208 Read More [PDF]… NIST announces the release of Special Publication (SP) 800-208, Recommendation for Stateful Hash-Based Signature Schemes. This publication supplements FIPS 186 by approving the use of two stateful hash-based signature schemes: the eXtended Merkle Signature Scheme (XMSS) and the Leighton-Micali Signature system (LMS) as specified in Requests for Comments […]

Global Quantum Leap Project to be Lead by U. of Minnesota
University of Minnesota to lead NSF-funded ‘Global Quantum Leap’ The University of Minnesota announced today that it will lead a five-year, $2 million grant from the National Science Foundation (NSF) to create an international “network-of-networks” that seeks to accelerate the discovery and development of quantum information systems. Quantum sciences are key to creating the next […]
Topological Magnetics Research Gets Real
Topology Gets Magnetic: The New Wave Of Topological Magnetic Materials Researchers demonstrate new high-throughput method for discovering magnetic topology The electronic structure of nonmagnetic crystals can be classified by complete theories of band topology, reminiscent of a “topological periodic table.” However, such a classification for magnetic materials has so far been elusive, and hence very […]
University of Copenhagen Researchers Strategize Entanglement Generation
The experimental demonstration of entanglement between mechanical and spin systems Read More… + “About a decade ago, we proposed a way to generate entanglement between a mechanical oscillator and a spin oscillator via photons, using the principle that was later called ‘quantum mechanics free subspaces’ or ‘trajectories without quantum uncertainties,’” said Eugene S. Polzik, who […]
U.S. Pacific Northwest National Laboratory Research Melding Electron Microscopy to Quantum Information Science
Enabling the Data-Driven Future of Microscopy We’re surrounded by an unseen atomic world that governs life and the technologies we use every day, such as batteries and computers. Scientists have developed powerful microscopes that use electron beams to peer into this world, revealing how tiny atomic motions and defects have a big impact on materials […]
