A new way to count qubits Researchers at Syracuse University, working with collaborators at the University of Wisconsin (UW)-Madison, have developed a new technique for measuring the state of quantum bits, or qubits, in a quan …
Charles Kao, Nobel-winning optical fiber pioneer, dies at 84 Charles K. Kao, who shared a 2009 Nobel Prize in physics for pioneering work in optical fiber technology that helped to lay the foundation for modern telecommunications, has died. He was 84.
Explainer: The US push to boost 'quantum computing' A race by U.S. tech companies to build a new generation of powerful "quantum computers" could get a $1.3 billion boost from Congress, fueled in part by lawmakers' fear of growing compet …
Newly discovered magnetic state could lead to green IT solutions Magnetic skyrmions are magnetic swirls that may lead to new solutions combining low-energy consumption with high-speed computational power and high-density data storage, revolutionizing information te …
Quantum anomaly—breaking a classical symmetry with ultracold atoms A FLEET study of ultracold atomic gases—a billionth the temperature of outer space—has unlocked new, fundamental quantum effects. The researchers at Swinburne University of Technology studied collecti …
Fiber optic sensor measures tiny magnetic fields Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain. The inexpensive and compact sensors could offer an al …
The hunt for leptoquarks is on Matter is made of elementary particles, and the Standard Model of particle physics states that these particles occur in two families: leptons (such as electrons and neutrinos) and quarks (which make u …
Researchers push the boundaries of optical microscopy The field of optical microscopy research has developed rapidly in recent years. Thanks to the invention of a technique called super-resolution fluorescence microscopy, it has recently become possible …
Extremely small and fast: Laser ignites hot plasma When light pulses from an extremely powerful laser system are fired onto material samples, the electric field of the light rips the electrons off the atomic nuclei. For fractions of a second, a plasma …
Searching for errors in the quantum world The theory of quantum mechanics is well supported by experiments. Now, however, a thought experiment by ETH physicists yields unexpected contradictions. These findings raise some fundamental questions …
Modified superconductor synapse reveals exotic electron behavior Electrons tend to avoid one another as they go about their business carrying current. But certain devices, cooled to near zero temperature, can coax these loner particles out of their shells. In extre …
Modeling crystal behavior—toward answers in self-organization The electrical and mechanical responses of crystal materials, and the control of their coupled effect, form one of the central themes in material science. They are vital to applications such as ultras …
New world record magnetic field A group of scientists at the University of Tokyo has recorded the largest magnetic field ever generated indoors—a whopping 1,200 tesla, as measured in the standard units of magnetic field strength.
