    Method with polarized light can create and measure nonsymmetrical states in a layered material

    Some molecules, including most of the ones in living organisms, have shapes that can exist in two different mirror-image versions. The right- and left-handed versions can sometimes have different properties, such that only one of them carries out the molecule’s functions. Now, a team of physicists has found that a similarly asymmetrical pattern can be induced and measured at will in certain exotic materials, using a special kind of light beam to stimulate the material. …read more

    Isotope movement holds key to the power of fusion reactions

    Fusion may be the future of clean energy. The same way the sun forces reactions between light elements, such as hydrogen, to produce heavy elements and heat energy, fusion on Earth can generate electricity by harnessing the power of elemental reactions. The problem is controlling the uniformity of hydrogen isotope density ratio in the fusion plasma—the soup of elements that will fuse and produce energy. …read more

    Study identifies a transition in the strong nuclear force that illuminates the structure of a neutron star’s core

    Most ordinary matter is held together by an invisible subatomic glue known as the strong nuclear force—one of the four fundamental forces in nature, along with gravity, electromagnetism, and the weak force. The strong nuclear force is responsible for the push and pull between protons and neutrons in an atom’s nucleus, which keeps an atom from collapsing in on itself. …read more

    Glass slides that stand to revolutionize fluorescence microscopy

    EPFL scientists have developed a new type of microscope slide that can boost the amount of light in fluorescence microscopy by a factor of up to 25. These new slides can both amplify and direct light, making them ideal for applications ranging from early-stage diagnosis to the rapid archiving of pathology samples. …read more

    Engineers ensure quantum experiments get off to the right start

    The quantum mechanical properties of electrons are beginning to open the door to a new class of sensors and computers with abilities far beyond what their counterparts based in classical physics can accomplish. Quantum states are notoriously difficult to read or write, however, and to make things worse, uncertainty about those states’ starting conditions can make experiments more laborious or even impossible. …read more

    The first quantum orienteering by quantum entangling measurements enhancement

    The CAS key lab of quantum information, led by Prof. Guo Guangcan, Li Chuanfeng, Xiang Guoyong and collaborators, reports enhancing the performance of quantum orienteering with entangling measurements via photonic quantum walks. These results were published online by Physical Review Letters on February 13th. …read more
