Optical Fiber Ion Trap Collects Light

Facebook X LinkedIn Email
GAITHERSBURG, Md., July 14, 2010 — Physicists at the National Institute of Standards and Technology (NIST) have demonstrated an ion trap with a built-in optical fiber that collects light emitted by single ions (electrically charged atoms), allowing quantum information stored in the ions to be measured. The advance could simplify quantum computer design and serve as a step toward swapping information between matter and light in future quantum networks. The new device is a 1-mm-square ion trap with a built-in optical fiber. The physicists use ions as quantum bits (qubits) to store information in experimental quantum...Read full article

    light
    Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
    optical fiber
    Optical fiber is a thin, flexible, transparent strand or filament made of glass or plastic used for transmitting light signals over long distances with minimal loss of signal quality. It serves as a medium for conveying information in the form of light pulses, typically in the realm of telecommunications, networking, and data transmission. The core of an optical fiber is the central region through which light travels. It is surrounded by a cladding layer that has a lower refractive index than...
