Moving Target Measured with Squeezed Light

Facebook Twitter LinkedIn Email
TOKYO, Sept. 24, 2012 — A novel quantum mechanical squeezing technique that precisely tracks the phase of optical waveforms in motion has broken the standard limits for ultraprecise measurement by exploiting quantum lightwaves in a different way. In optical communications, information is often stored in a waveform or light pulse. Yet noise and fluctuations arise, causing random jitter in the phase and amplitude of optical pulses, making it difficult to keep track of waveform phase. Squeezed light can be used to make measurements of very small distances, and now scientists at the University of Tokyo and...Read full article

    1. In relation to cathode-ray tube displays, errors in the signal's amplitude, phase or both that result in small, rapid aberrations in size or position of the image. 2. Errors of synchronization between a facsimile's transmitter and receiver that are characterized by a raggedness in the copy. 3. Small spurious variations in a waveform, such as in pulse repetition rate, amplitude, frequency or phase, that stem from supply-voltage variations, mechanical instability and other factors.
    optical communications
    The transmission and reception of information by optical devices and sensors.
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
